Thermoreversible Gels as Magneto‐Optical Switches

Abstract

Polyfunctional gels: Thermoreversible switchable gels with tunable magnetic, optical, and rheological properties are obtained from a modified spin-crossover polymeric precursor and alkane solvents (see picture). The iron triazole polymer which acts as the gelator, undergoes a spin crossover that is accompanied by a change in the color of the gel. The transfer of spin-crossover properties from solid materials into gels offers a route to new applications.
