Electrically Conductive Metal–Organic Frameworks

Chemical Reviews, Journal Year: 2020, Volume and Issue: 120(16), P. 8536 - 8580

Published: April 10, 2020

Metal-organic frameworks (MOFs) are intrinsically porous extended solids formed by coordination bonding between organic ligands and metal ions or clusters. High electrical conductivity is rare in MOFs, yet it allows for diverse applications electrocatalysis, charge storage, chemiresistive sensing, among others. In this Review, we discuss the efforts undertaken so far to achieve efficient transport MOFs. We focus on four common strategies that have been harnessed toward high conductivities. "through-bond" approach, continuous chains of bonds centers ligands' functional groups create pathways. "extended conjugation" metals entire form large delocalized systems. The "through-space" approach harnesses π-π stacking interactions moieties. "guest-promoted" utilizes inherent porosity MOFs host-guest interactions. Studies utilizing less defined pathways also evaluated. For each give a systematic overview structures properties relevant materials. consider benefits limitations developed thus provide an outstanding challenges conductive

Metal–Organic Framework-Based Hierarchically Porous Materials: Synthesis and Applications

Chemical Reviews, Journal Year: 2021, Volume and Issue: 121(20), P. 12278 - 12326

Published: July 19, 2021

Metal-organic frameworks (MOFs) have been widely recognized as one of the most fascinating classes materials from science and engineering perspectives, benefiting their high porosity well-defined tailored structures components at atomic level. Although intrinsic micropores endow size-selective capability surface area, etc., narrow pores limit applications toward diffusion-control large-size species involved processes. In recent years, construction hierarchically porous MOFs (HP-MOFs), MOF-based composites, derivatives has captured widespread interest to extend conventional materials. this Review, advances in design, synthesis, functional are summarized. Their structural characters various applications, including catalysis, gas storage separation, air filtration, sewage treatment, sensing energy storage, demonstrated with typical reports. The comparison HP-MOFs traditional (e.g., zeolite, silica, carbons, metal oxides, polymers), subsisting challenges, well future directions research field, also indicated.
