Abstract:In the search for multifunctional molecular materials, we designed an enantiopure pair of Fe-II complexes with chiral, chelating (R)/(S)-4,5-pinenepyridyl-2-pyrazine ligands exhibiting three inherent physical properties: chirality, spin crossover, and dielectric switching. The geometrical change resulted in coupling of the spin-crossover transition at 187 K to dielectric switching. Both compounds were found to display light-induced spin crossover that was thermally unstable above ca. 40 K. The coupling of two hysteretic properties, electric and magnetic, renders these compounds as potential switching devices.
