WHITE LIGHT EMITTING ZIRCONIUM-BASED MOFS

摘要

A composite material emitting white light includes a MOF having a plurality of organic polydentate bridging ligands and a plurality of zirconium cations. The composite material includes at least one guest dye capable of absorbing energy in a wavelength range emitted by the MOF when the MOF is excited. The at least one guest dye includes 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. The composite material emitting white light is also used in sensors and imaging.
