Ultraviolet-emitting conjugated polymer poly(9,9'-alkyl-3,6-silafluorene)with a wide band gap of 4.0 eV

摘要

An ultraviolet-emitting conjugated polymer,poly(9,9'-alkyl-3,6-silafluorene)with a wide band gap of 4.0 eV,has been synthesized and characterized.Violet and ultraviolet(UV)light-emitting polymers have attracted great interest because they can be used to generate emission over the whole visible range and white light emission either by the irradiation of luminescent dyes or via energy transfer from host materials to emissive dopants,especially phosphorescent dyes.
