Hysteretic Three-Step Spin Crossover in a Thermo- and Photochromic 3D Pillared Hofmann-type Metal-Organic Framework

Multistability is exhibited by a metal–organic framework material that undergoes unique three‐step spin crossover with 20 K thermal hysteresis (see picture). The stepwise transition is coupled to a three‐step structural transformation that defines four distinct structural states. The material also e...

Summary:Multistability is exhibited by a metal–organic framework material that undergoes unique three‐step spin crossover with 20 K thermal hysteresis (see picture). The stepwise transition is coupled to a three‐step structural transformation that defines four distinct structural states. The material also exhibits reversible photo‐induced spin crossover.
