The invention relates to a tetra-branched rare earth complex and a preparation method thereof. The complex is prepared through complexing reaction of three ligands, namely two M1s and one M2 by taking a trivalent rare earth ion as a central ion. The chemical formula of the complex is Ln(M1)2M2, wherein Ln is the rare earth ion; M is the ligands consisting of M1 and M2; M1 is a monocarboxylic compound synthesized by a tetratomic alcohol compound and an aliphatic or aromatic dicarboxylic compound; M2 is 1,10-phenanthroline; and a ligand solvent is dimethyl sulfoxide or N,N-dimethyl formamide. The rare earth complex of the invention has a network pore structure, bigger conjugate plane, better rigid structure and structural stability, and more coordinative rare earth ions. A rare earth polymer luminescent material synthesized by the tetra-branched rare earth complex has no phenomenon that ions are accumulated to form ion clusters so as to cause fluorescent quenching, and can effectively perform ...
