Photoinduced reversible spin-state switching of an FeIII complex assisted by a halogen-bonded supramolecular network

Abstract

The organization of a molecular Fe^III complex embedded in a halogen-bonded 2D network is chemically tuned to trigger temperature- and light-induced spin-state switching. We attribute the associated magnetic properties and the unprecedented photoswitching effect to the optimized structural confinement provided by the presence of the supramolecular host framework.
