Self-assembly of functional liquid crystals provides a powerful approach to the development of stimuli-responsive materials and interfaces. Here, we have designed and synthesized bioconjugated amphiphilic dendritic mesogens containing arginine–glycine–aspartic acid (RGD) peptide sequence to develop new biofunctional aqueous/liquid crystalline interfaces. We have found that the RGD peptide-conjugated forklike mesogens induce the homeotropic alignment of liquid crystals at the aqueous interfaces, leading to distinct optical changes caused by the specific binding of the target proteins. In contrast, no response to the target protein is observed for the interfaces prepared with the RGD peptide-conjugated single mesogen. Molecular insights into the orientation and stimuli-responsiveness of the bioconjugated mesogens at the interfaces are obtained based on measurements of the Langmuir films and self-assembled properties of these molecules. These results demonstrate that the number of rodlike cores of the bioconjugated mesogens affects the monolayer structures formed at the aqueous interface as well as the liquid crystalline properties. We propose a new molecular design of bioconjugated mesogens to couple biomolecular interactions at the aqueous interfaces with the ordering transition of the liquid crystals. These materials have the potential to tailor the responsiveness of liquid crystalline interfaces for biomolecular sensing.

The air/liquid interface is a superior platform to create nanosheets of materials by promoting spontaneous two-dimensional growth of components. Metal–organic frameworks (MOFs)—intrinsically porous crystals—with π-conjugated triphenylene-based ligands show high electrical conductivities. Forming nanosheets of such conductive MOFs should enable their use in electronic devices. Although highly conductive MOF nanosheets have been created at the air/liquid interface, direct control of their continuity, morphology, thickness, crystallinity, and orientation directly influencing device performance remains as an issue to be addressed. Here, we present detailed insights into the formation process of electrically conductive MOF nanosheets composed of 2,3,6,7,10,11-hexaiminotriphenylene (HITP) and Ni2+ ions (HITP-Ni-NS) at the air/liquid interface. The morphological and structural features of HITP-Ni-NS strongly depend on the standing time—the time without any external actions involved, but leaving the interface undisturbed after setting the ligand solution onto the metal-ion solution. We find that the fundamental features of HITP-Ni-NS are determined by the standing time with conductivity sensitively influenced by such pre-determined HITP-Ni-NS characteristics. These findings will lead towards the establishment of a rational strategy for creating MOF nanosheets at the air/liquid interface with desired properties, thereby accelerating their use in diverse potential applications.

Metal–organic frameworks (MOFs)─crystalline coordination polymers─with unique characteristics such as structural designability accompanied by tunable electronic properties and intrinsic uniform nanopores have become the platform for applications in diverse scientific areas ranging from nanotechnology to energy/environmental sciences. To utilize the superior features of MOF in potential applications, the fabrication and integration of thin films are of importance and have been actively sought. Especially, downsized MOFs into nanosheets can act as ultimately thin functional components in nanodevices and potentially display unique chemical/physical properties rarely seen in bulk MOFs. Assembling nanosheets by aligning amphiphilic molecules at the air/liquid interface has been known as the Langmuir technique. By utilizing the air/liquid interface as a reaction field between metal ions and organic ligands, MOFs are readily formed into the nanosheet state. The expected features in MOF nanosheets including electrical conduction largely depend on the nanosheet characteristics such as lateral size, thickness, morphology, crystallinity, and orientation. However, their control has not been achieved as yet. Here, we demonstrate how changing the concentration of a ligand spread solution can modify the assembly of MOF nanosheets, composed of 2,3,6,7,10,11-hexaiminotriphenylene (HITP) and Ni2+ ions (HITP-Ni-NS), at the air/liquid interface. A systematic increase in the concentration of the ligand spread solution leads to the enlargement of both the lateral size and the thickness of the nanosheets while retaining their perfect alignment and preferred orientation. On the other hand, at much higher concentrations, we find that unreacted ligand molecules are included in HITP-Ni-NS, introducing disorder in HITP-Ni-NS. These findings can develop further sophisticated control of MOF nanosheet features, accelerating fundamental and applied studies on MOFs.

Covalent organic frameworks (COFs) are crystalline organic materials with high porosity. The COFs are typically electrical insulators because of their wide bandgaps and closed-shell structures despite their π–π layer stacking motif suitable for carrier conduction. Here, we report a strategy for realizing tunable electrical conductivity in COFs by intercalating redox-active guest molecules. The approach is demonstrated using COF-5 with a boronate-ester-linked two-dimensional structure and one-dimensional nanopore channels infiltrated by 7,7,8,8-tetracyanoquinododimethane (TCNQ). Successful incorporation of guest TCNQ molecules into the cavities of the COF-5 host is confirmed by vibrational and optical spectroscopies and results in the appearance of guest–host charge-transfer transitions for TCNQ-intercalated COF-5. Overall electrical conductivities are enhanced by the carrier generation induced by the charge transfer between TCNQ and COF-5 with the retained layer-stacked structures in COF-5 also contributing to the conduction pathways. The tunable electronic properties of COFs realized by the host–guest strategies established here will further promote refinement of design principles of conductive COFs and deeper understanding of the conduction mechanism while simultaneously providing opportunities for using COFs in diverse applications.

Nanosheets of metal–organic frameworks (MOFs)—porous crystalline materials consisting of metal ions and organic ligands—are actively studied for their intrinsic chemical/physical properties attributed to the reduced dimensionality and for their potential to function as ideal components of nanodevices, especially when electrical conduction is present. Air/liquid interfacial synthesis is a promising technique to obtain highly oriented MOF nanosheets. However, rational control of size and shape combined with the aimed functionality remains an important issue to address making it necessary to research the critical factors governing nanosheet characteristics in the interfacial synthesis. Here, we investigate the influence of the solvent—methanol (MeOH) versus N,N-dimethylformamide (DMF)—used to prepare a ligand spread solution on an assembly of MOF nanosheets composed of Ni2+ and 2,3,6,7,10,11-hexaiminotriphenylene (HITP) (HITP-Ni-NS). We find that the macroscopic morphological uniformity in the micrometer scale is higher when DMF is used as the solvent. Regarding the microscopic crystalline domain, molecules of DMF with relatively high polarity and boiling point are involved in HITP-Ni-NS formation, hindering its growth and resulting in nanosheets with slightly smaller lateral size than that grown when MeOH is used. These findings provide crucial guidelines towards establishing a judicious strategy for creating desired MOF nanosheets at the air/liquid interface, thereby driving forward research on both fundamental and applied aspects of this field.

DMF leads higher morphological uniformity in HITP-Ni-NS at the micrometer scale and moderates its growth, resulting in smaller lateral crystalline size than that of nanosheets grown with MeOH as the solvent.

Air-stable single-component ambipolar organic semiconductors that conduct both holes and electrons are highly desired but have been rarely realized. Neutral nickel bis(dithiolene) complexes are promising candidates that fulfill the stringent electronic requirements of shallow HOMO levels and deep LUMO levels, which can reduce the carrier injection barrier to overcome the work function of gold electrodes and ensure air stability. However, most nickel bis(dithiolene) analogs that have been characterized as ambipolar semiconductors have twisted molecular structures that hinder the effective intermolecular interactions required for carrier conduction. To address this issue, we synthesized planar alkoxy-substituted nickel bis(dithiolene) analogs that facilitate dense packing with effective intermolecular interactions. Remarkably, changing the methoxy substituents to ethoxy or propoxy groups led to a dramatic change in the packing mode, from one-dimensional to herringbone-like, while maintaining effective intermolecular interactions. These materials overcome the usual trade-off between crystallinity and solubility; they are highly crystalline, even in their film forms, and are highly soluble in organic solvents. They are therefore readily solution-processable to form semiconducting layers with well-defined and well-ordered structures in field-effect transistors. Devices based on these compounds exhibited efficient ambipolar characteristics, even after several months of exposure to air, achieving high carrier mobilities of up to 10–2 cm2 V–1 s–1 and large on/off ratios of up to 105, which are the top-class performances achieved for a single-component ambipolar semiconductor material driven in air.
 "Metal-organic Framework and Hydrogen-bonded Organic Framework Nanosheets Assembled at Air/Water Interfaces — Synthesis, Characterizations and Applications"
Zeolite, 39(3), 96-111 (2022).
Published: 15 July 2022
Sheet-like nanomaterials with thicknesses ranging from a few nanometers to a dozen nanometers are called nanosheets. Since they are the ultimate thin functional materials, they contribute to miniaturize various devices/products and resource conservation. Many nanosheets reported so far are produced by exfoliating macro-scale materials. This requires many processes such as synthesis of macro-scale crystals under high temperature and high pressure, exfoliation, preparation of dispersion solutions for exfoliated materials (nanosheets), and film formation of exfoliated nanosheets. In addition, the exfoliation process requires chemical or physical stimulations such as sonication under existence of solvents or grinding which causes degradation and re-agglomeration of the nanosheets. We have developed a simple method by utilizing air/water interfaces for creating molecular nanosheets. The major process is dropping a solution containing organic molecules, which are the building blocks of nanosheets, onto a water surface at room temperature. With the air/water interfacial synthesis, we have succeeded in creating nanosheets of crystalline and porous coordination polymers (MOFs: metal-organic frameworks) and hydrogen-bonded organic frameworks (HOFs: hydrogen-bonded organic frameworks). Organic molecules spread at the air/liquid interface connect each other in a two-dimensional direction and align regularly, resulting in formation of crystalline nanosheets with uniform nanopores. These nanosheets are stable without aggregation at the air/water interface and can be transferred to various substrates depending on the required application while retaining their porous structure. Such nanosheets with regularly arranged molecules and nanopores of uniform shape and size can be used diverse applications including high-performance separation membranes, thin film solar cells, molecular sensors and electrodes of batteries. In this article, detailed synthetic procedures of MOF and HOF nanosheets using the air/water interface are explained together with their characterization methods and potential applications.

Over the past decade, significant progress has been made in research on metal–organic frameworks (MOFs) – highly ordered microporous materials composed of metal ions and organic linkers – resulting in an increased understanding of the relationship between framework structure/components and performance in various applications in diverse fields such as electronics, energy creation/storage and biomaterials. For most potential applications, organizing MOFs into two-dimensional (2D) thin films – nanosheets – is necessary. In order to create MOF nanosheets, two experimental approaches have been developed: top-down and bottom-up and most review papers on MOF nanosheets deal with these two methods. In this review, I focus on the bottom-up approach for creation of MOF nanosheets, a simple process with one or few steps that potentially offers access to large nanosheets with macroscopic continuity. Especially, the Langmuir-Blodgett (LB) methodology utilizing air/liquid interfaces is sequentially discussed. Because of the ultrathin state of nanosheets, characterization methods of MOF nanosheets often differ from those employed for bulk MOF crystals conducted with conventional techniques. Therefore, representative and useful techniques to determine nanosheet characteristics are explained in detail. Following that, I discuss the structural and morphological development of porphyrin- and triphenylene-based MOF nanosheets that critically influences their chemical/physical properties. Finally, I describe challenges and perspectives related to the LB synthesis towards further understanding of the growth mechanism at the interfaces, leading to extensive applications of MOF nanosheets.

Although most metal–organic frameworks (MOFs)—highly porous crystalline metal complex networks with structural and functional varieties—are electrically insulating, high electrical conduction has been recently demonstrated in MOFs while retaining permanent porosity. Usability of electronically active MOFs effectively emerges when they are created in a thin-film state as required in major potential applications such as chemiresistive sensors, supercapacitors, and electrode catalysts. Thin-film morphology including crystallinity, thickness, density, roughness, and orientation sensitively influences device performance. Fine control of such morphological parameters still remains as a main issue to be addressed. Here, we report a bottom-up procedure of assembling a conductive MOF nanosheet composed of 2,3,6,7,10,11-hexaiminotriphenylene molecules and nickel ions (HITP-Ni-NS). Creation of HITP-Ni-NS is achieved by applying air/liquid (A/L) interfacial bottom-up synthesis. HITP-Ni-NS has a multilayered structure with 14 nm thickness and is endowed with high crystallinity and uniaxial orientation, demonstrated by synchrotron X-ray crystallography. Facile transferability of HITP-Ni-NS assembled at air/liquid interfaces to any desired substrate enables us to measure its electrical conductivity, recorded as 0.6 S cm-1—highest among those of triphenylene-based MOF nanosheets with a thickness lower than 100 nm.

Molecular arrangements of amphiphilic mesogens with tripeptides in monolayers assembled at air/water interfaces are studied. Because of bent structures, the amphiphilic mesogens exist in the liquid-expanded state. The measurements of atomic force microscopy and water contact angle of monolayers transferred on silicon imply that the rigid-rod moieties initially lie on the substrate then rise up by applied surface pressure.

Electrocatalytic oxygen reduction reaction (ORR) and hydrogen evolution reaction (HER) are vital in the renewable energy platform, particularly fuel cells and rechargeable batteries, where construction of efficient electrocatalysts is a crucial task. In contrast to noble-metal catalysts, heteroatom-doped carbons have recently emerged as new-generation electrocatalysts because of their low cost and high stability/activity. Although unique features of covalent organic frameworks (COFs) including high surface areas, adjustable apertures, and easy introduction of diverse heteroatoms render them promising precursors for heteroatom-doped carbons, development of electrocatalysts derived from COFs with simultaneously high activities of ORR/HER is still at an early stage. Here, we report the creation of metal-free heteroatom-doped carbon catalysts derived from four types of newly designed nanoporous two-dimensional COFs with ordered pores smaller than 1 nm. Both preincorporated N in the pristine COFs and postdoped P heteroatoms are uniformly distributed into the graphitized carbons and functioning as effective active sites for electrocatalysis. Furthermore, the obtained heteroatom (N, P) codoped carbons possess nanoporosity beneficial for efficient introduction of reactants. Therefore, the N, P codoped nanoporous carbons demonstrate robust electrochemical performances for both ORR and HER with a half-wave potential of 0.81 V in alkaline medium and low overpotential of 260 mV in acid solutions. In addition, their catalytic activities are not changed after a long-time cycle. These findings will promote creation of robust COF-derived carbon catalysts in energy storage and conversion as well as development of new COFs with tunable nanopores.

The influence of synthetic conditions on the shape and size of SrTiO3 (STO) nanocubes was studied. These were synthesized in aqueous solution using Sr(OH)2 as the Sr2+ source and titanium(IV) bis(ammonium lactate)dihydroxide (TALH) as the TiIV source in the presence of oleic acid and hydrazine. A large excess of OH− at a pH of the precursor solution higher than 12 is necessary for the formation of STO nanocubes without the need for any calcination. Performing the synthesis in a N2 atmosphere additionally prevents the formation of SrCO3 impurity, leading to the creation of uniformly sized STO nanocubes in a reproducible manner. Such size-regulated STO nanocubes are found to align over a large area.
