Homopolymer(PBIP) containing 2,6-bis(1’-methylbenzimidazolyl)pyridine(Me BIP) ligands in the side chain was synthesized by RAFT polymerization and its kinetics was studied. Polymeric complex PBIP-Nd~(3+) was prepared by chelating PBIP with lanthanide ion Nd~(3+). The homopolymers and PBIP-Nd~(3+) complex were investigated by NMR, FTIR, GPC and TGA. The optical property of PBIP-Nd~(3+) complex was characterized by UV-Vis spectroscopy. The magnetic property of PBIP-Nd~(3+) complex was measured as a function of temperature(5 K to 300 K) and as a function of field(-3.98×10~6 A/m to 3.98×10~6 A/m). These results indicated that PBIP-Nd~(3+) complex is paramagnetic. Polymeric complex PBIP-Nd ~ (3+) was prepared by RAFT polymerization and its kinetics was studied by chelating PBIP with lanthanide ion Nd ~ (3+). The homopolymers and PBIP-Nd ~ (3+) complexes were investigated by NMR, FTIR, GPC and TGA. The optical property of PBIP-Nd ~ (3+) complex was characterized by UV-Vis spectroscopy. The magnetic property of PBIP-Nd ~ (3+) complex was measured as a function of temperature (5 K to 300 K) and as a function of field (-3.98 × 10 -6 A / m to 3.98 × 10 ~ 6 A / m). These results indicated that PBIP-Nd ~ (3+) complex is paramagnetic.
