A photochromic naphthalene diimide coordination network sensitized by polyoxometalates†
Abstract
Metal-ion-directed assembly of naphthalene diimide tectons cooperatively enhanced by anion–π interactions of giant anions, PMo12O403−, leads to a novel organic–inorganic hybrid with ultrafast-responsive photochromic properties, which is attributed to the polyoxometalate-sensitized photo-induced radical generation of naphthalene diimide units.
