Unconjugated organic phosphorus, oxide and rare earth coordination polymer as well as preparation method and application thereof

Abstract

The invention provides an unconjugated organic phosphorus, oxide and rare earth coordination polymer as well as a preparation method and application thereof, which relate to an organic phosphorus, oxide and rare earth coordination polymer as well as a preparation method and application thereof and solve the problems that the traditional rare earth electroluminescent coordination polymer has large preparation difficult, long cycle, unstable quality and property, low brightness and efficiency, and the like. The polymer has the structural formula that the polymer can be prepared by using a polymerizable organic phosphorus, oxide and rare earth compound and vinyl carbazole as monomers and copolymerizing by free radicals; the polymerizable organic phosphorus, oxide and rare earth compound monomer is prepared from a polymerizable organic phosphorus and oxide compound neutral ligand, a beta-diketone anion ligand and rare earth center metal ions through matching reaction. The polymer is used for the luminescent layer material or the luminescent layer doping material of an electroluminescent device. The light starting voltage of the manufactured electroluminescent device is 12.5-21V, and the electroluminescent brightness is 15-150cd/m<2>. The polymer can be used as an electric active layer of a polymer electric storing device. The cycle of the method is short.
