The polymeric ligand PBIa (functionalized polybenzimidazole containing β-diketone side group) was successfully synthesized via the reaction of polybenzimidazole (PBI) with 3-Br-acetylacetone in DMSO solvent using NaH as the deprotonation reagent. Its corresponding polymeric complexes of Dy3+ and Gd3+ were prepared and characterized by FT-IR, 1H NMR, molar conductance measurements, and thermal analysis. The photoluminescence properties and the probable mechanism of the Dy and Gd complexes were studied. The measurement and analysis of the thermal properties showed that these were thermal stable.
