Problems solved by technology

However, in the reported bonded polymer-rare earth complex luminescent material systems, most of the ligands participating in the coordination in the polymer side chain are aliphatic carboxyl groups (mainly from monomeric acrylic acid or methacrylic acid), and aliphatic carboxyl groups It only plays the role of coordination and chelation for rare earth ions, without the function of sensitization (that is, "Antenna" effect). It needs to add small molecule ligands that cooperate with coordination to form luminescent materials (Suo Q l, Lu F, Shi J W ,Hong H L, Luo J P. Journal of Rare Earths, 2009,27:28), which largely limits the luminescent properties of this type of functional materials

Abstract

The invention relates to the field of bonded high molecule-rare earth complex luminescent materials, and relates to a preparation method of a functional polysulfone-Tb (III) ion complex luminescent material. According to the invention, a bidentate Schiff base ligand with coordination chelation and sensitization luminescent dual functions is synthesized and bonded on the side chain of polysulfone. The Schiff base ligand can coordinate with rare earth Tb (III) ion to form a stable high molecule-rare earth complex, and has a conjugated aromatic ring. The Schiff base ligand has high light absorption performance, can considerably generate intramolecular energy transfer, and can strongly sensitize the fluorescence emission of rare earth Tb (III) ion. Therefore, the photo-luminescent material emitting green light can be successfully obtained.
