Abstract

The invention discloses an azo polyarylether rare earth complex material as well as a preparation method and an application thereof, and belongs to the technical field of polymer materials. The azo polyarylether rare earth complex is obtained by utilizing an azo polyarylether copolymer with carboxyl as a macromolecular ligand, utilizing phenanthroline as a co-ligand and carrying out ion coordination synthesis on the macromolecular ligand and the co-ligand with rare earth europium or terbium. The polyarylether copolymer is prepared by performing nucleophilic polycondensation on azo bisphenol monomer, difluoro monomer and 4, 4'-dihydroxy triphenyl methane-2-carboxylic acid bisphenol monomer as raw materials. The azo polyarylether rare earth complex material can be used for preparing surface relief gratings or fluorescent patterns, and the colors of the fluorescent patterns can be changed by changing the category of the rear earth ions. The prepared azo polyarylether rare earth complex fluorescent patterns have an application prospect in holographic storage and light emitting devices.
