Belonging to the field of high polymer-rare earth composite luminescent materials, the invention in particular relates to an aminophenol type bidentate Schiff base ligand functional polymer-rare earth complex luminescent material and a preparation method thereof. The method includes: introducing an aminophenol type bidentate Schiff base ligand with coordination and sensitization dual functions to rare earth ions into a polymer side group, and then conducting coordination with rare earth ions to obtain an aminophenol type bidentate Schiff base ligand functional polymer-rare earth binary complex luminescent material, then subjecting the complex to supplementary coordination with small molecular ligand phenanthroline or 2, 2'-bipyridyl respectively, thus obtaining an aminophenol type bidentate Schiff base ligand functional polymer-rare earth ternary complex luminescent material. The method is easy to realize, and solves the problems of uneven dispersion of rare earth complex, poor performance of the polymer matrix and the like in the prior art, and opens up a new way for preparation of novel high polymer-rare earth luminescent materials.
