Photomagnetic Effects in Polycyanometallate Compounds: An Intriguing Future Chemically Based Technology?

Abstract

Out of the blue: Photoinduced magnetism in polymeric “Prussian Blue” analogues is a well understood phenomenon that can even occur near room temperature. The lessons learned are now being transferred to the synthesis of molecular cyanide-bridged single-molecule magnets (see picture; Mo yellow, C black, N blue, Cu purple) whose magnetic properties change drastically on light irradiation.
