Charge and spin control based on coordination chemistry

Abstract

Design of multiply sensing materials whose intrinsic nature is mutually tunable by chemical and physical external stimuli is a pivotal challenge in the field of materials science. A class of electron-conjugated metal-organic frameworks (MOFs) composed of electron-donors (D) and/or -acceptors (A) as “D/A-MOFs” is one of the favorable candidates for such materials. Since the charge transfer of D0A0 ↔ Dδ+Aδ- is flexible as a function of the combination of the ionization potential of D and the electron affinity of A and the Madelung packing stabilization of the ionic D+A- set, D/A-MOFs are intriguing targets for guest-sensitive functional materials with magnetic, conducting, and their synergistic properties, as well as with their porous nature for gas/solvent sorption or ionic transportation.
