WHITE LIGHT EMITTING ZIRCONIUM-BASED MOFS

摘要

The present invention is directed to composite material emitting white light comprising a MOF comprising a plurality of organic polydentate bridging ligands and a plurality, characterized in that said composite material comprises at least one guest dye capable of absorbing energy in a wavelength range emitted by the MOF when said MOF is excited, said at least one guest dye comprising a chromophore selected from the group consisting of a naphthoxazinium group, an aromatic cyclobutdione group, a 1-benzopyran-2-one group, xanthenylidene-dialkylammonium group, a porphyrin group or a 4-dimethylaminostyryl group a boron-dipyrromethene group and mixtures thereof. It also refers to its use in the emission of white light, sensors and imaging.
