Abstract

Abstract : Thermally‐induced simultaneous switching of magnetism and electrical conductivity has been realized by a two‐dimensional supramolecular coordination assembly composed of Fe II spin‐crossover complexes and partially charged TCNQ (7, 7', 8, 8'‐tetracyano‐ p ‐quinodimethane) radicals. Fe II spin‐crossover units are directly linked to π‐stacked TCNQ columns, thus possessing strongly coupled magnetism (from localized d electrons) and electrical conductivity (from delocalized π electrons). This result was further supported by the observation of a magnetoresistance effect. More information can be found in the Full Paper by R. Ishikawa et al. on page 1278 .
