Functionalized polyoxometalates with intrinsic photochromic properties and their association with spiropyran cations

Abstract

International audienceThe presence of alkylammonium groups covalently grafted on bisphosphonato ligands induces photochromic properties to ligand-coordinated polyoxomolybdate systems. Such intrinsically photoactive polyanions can be used for the preparation of materials combining photochromic polyoxometalates and functional countercations
