Abstract Metal‐organic frameworks (MOFs) are a specific class of hybrid, crystalline, nano‐porous materials made metal‐ion‐based ‘nodes’ and organic linkers. Most the studies on MOFs largely focused porosity, chemical structural diversity, gas sorption, sensing, drug delivery, catalysis, separation applications. In contrast, much less reports paid attention to understanding tuning electrical properties MOFs. Poor conductivity (~10 −7 –10 −10 S cm −1 ), reported in earlier studies, impeded their applications electronics, optoelectronics, renewable energy storage. To overcome this drawback, MOF community has adopted several intriguing strategies for electronic The present review focuses creatively designed bulk surface‐anchored (SURMOFs) with different metal nodes (from transition metals lanthanides), ligand functionalities, doping entities, allowing enhancement conductivity. Diverse platforms MOFs‐based device fabrications, measurements, underlying charge transport mechanisms also addressed. Overall, highlights pros cons electronics (MOFtronics), followed by an analysis future directions research, including optimization compositions, heterostructures, contacts, stacking, further relevant options which can be interest researchers result improved devices performance.

Abstract Mimicking biological proton pumps to achieve stimuli‐responsive protonic solids has long been of great interest for their diverse applications in fuel cells, chemical sensors, and bio‐electronic devices. Now, dynamic light‐responsive metal–organic framework hybrid membranes can be obtained by situ encapsulation photoactive molecules (sulfonated spiropyran, SSP), as the molecular valve, into cavities host ZIF‐8. The configuration SSP changed switched reversibly response light, generating different mobile acidic protons thus high on/off photoswitchable conductivity device. This device exhibits a conductivity, fast time, extremely large ratio upon visible‐light irradiation. approach might provide platform creating emerging smart with potential remote‐controllable sensors or proton‐conducting field‐effect transistors.

Metal-organic frameworks (MOFs) are a class of crystalline porous coordination materials, which assembled from inorganic nodes and organic linkers. Numerous applications, such as gas storage, molecule separation, catalysis, optical sensing, charge transport, benefit the outstanding properties MOF materials. More advanced e.g., in electronics optoelectronics area, demand homogeneous monolithic thin films. Recent studies demonstrated that surface-mounted MOFs (SURMOFs) well suited to fulfill requirements for integration into devices. As thin-film material with tunable thickness, SURMOFs have been widely used optimization chromophore stacking, electrical stimuli-response, etc. The fabrication is carried out employing layer-by-layer (LbL) assembly technique, it can yield films well-defined orientation, editable heterostructure. We summarize LbL methods SURMOF realization architectures, including electronic applications photoactive SURMOF-derived materials technical conclude discussion challenges prediction future

The ability to dynamically control chirality remains a grand challenge in chemistry. Although many molecules possess chiral isomers, lacking their isolation, for instance during photoisomerization, results racemic mixtures with suppressed enantiospecific properties. Here, we present nanoporous solid which and enantioselective enrichment is induced by circularly polarized light (CPL). material based on photoswitchable fluorinated azobenzenes attached the scaffold of crystalline metal-organic framework (MOF). azobenzene undergoes trans-to-cis-photoisomerization upon irradiation green reverts back trans violet light. While each moiety cis conformation chiral, show isomer also possesses nonplanar, conformation. During photoisomerization unpolarized light, no enantiomeric observed both R- S-cis as well S-trans, respectively, are formed identical quantities. In contrast, CPL causes photoresolution, resulting an optically active material. Right-CPL selectively excites R-cis R-trans enantiomers, producing MOF enriched S-enantiomers, vice versa. induction optical activity reversible only depends light-handedness. As shown first-principle DFT calculations, while both, cis, stabilized conformations MOF, adopts planar, achiral form solution, verified experimentally. This shows that photoresolution enabled linker reticulation MOF. Our study demonstrates materials opens new opportunities resolution information storage CPL.
