Abstract

Abstract : A series of polyoxometalate-based host–guest materials emit strong red room-temperature phosphorescence attributed to intermolecular charge-transfer states which was caused by unorthodox anion–π interactions. Abstract : A series of host–guest materials containing polyoxometalate anions and lanthanide-organic layers have been synthesized and structurally characterized. By anion–π interactions between the anions and the π-acidic naphthalenediimide moieties, the materials emit strong red room-temperature phosphorescence and exhibit reversible photochromism.
