We design new solid-state photochromic materials that exhibit reversible light-induced color changes. These systems are of great interest in a wide range of marketable applications (pigments for paints and windows, cosmetics, UV sensors), and other promising technological applications in photonic (optical switches, 3D high-density optical data storage). Our materials are built upon POMs associated with a wide range of organic molecules. They develop remarkable photoinduced optical properties in the solid state that associate the generation of excitons into the POM with electron transfers – and sometimes atom displacement – at the organic-inorganic interface. The developed themes are summarized below.
