The reversible self-assembly behavior of thermoresponsive γ-shaped polymer can be effectively tuned based on the inclusion complexation, intermolecular hydrogen bonding and steric hindrance of β-CD.

While the metallocene polymers were comprehensively studied, other metallopolymers are rarely explored. The major challenge is the lack of a synthetic platform for the preparation of metal coordinated derivatives, monomers, and polymers. Therefore, the development of a facile synthesis of new metal coordinated monomers and polymers is critically needed. A novel successfully synthesized methacrylate-containing nickel complex is reported in this communication. Controlled RAFT polymerizations are further carried out to prepare a series of side-chain nickel containing polymers with different molecular weight and narrow Polydispersity Index (PDI). This new metallopolymer performs specific electrochemical and excellent thermal properties. This study provides a novel and convenient strategy to prepare metallopolymer with controllable molecular weight, which has potential applications in assembled, catalytic and magnetic materials.

Poly[6-(2,6-bis(1 0 -methylbenzimidazolyl)pyridin-4-yloxy)hexyl acrylate] (PBIP) and its terbium complex (PBIP-Tb 31 ) were prepared and characterized by 1 H NMR and FT-IR. The optical properties of PBIP-Tb 31 complex were characterized by UV-vis spectroscopy and fluorescence spectroscopy. Both polymer PBIP and PBIP-Tb 31 complex show good thermal stability. The magnetic property of PBIP-Tb 31 complex was measured as a function of temperature (5-300 K) at 30 kOe and as a function of an external field (250 to 50 kOe) at 5 K. Magnetic hysteresis loop of PBIP-Tb 31 complex at 5 K shows typical "S" shape and PBIP-Tb 31 complex is soft ferromagnetic.
