| 英文摘要 | A new terpyridine-functionalized dithioester was synthesized as a chain transfer agent in the reversible addition fragmentation chain transfer polymerization (raft) of n-isopropylacyamide (nipaam). the polymerization showed an first-order kinetics and the molecular weight increased linearly with conversion, indicating that the terpyridine-functionalized dithioester is an efficient chain transfer agent for the raft polymerization of nipaam. the terpyridine-functionalized poly (n-isopropylacyamide) (tpy-pnipaam) not only displays similar phase transition as pnipaam, but also have the coordination ability via terpyridine, which were further used to construct macromolecular-metal complex with ferrous ions as model metal ions. the appearance of a strong absorption at 555 nm in uv-vis spectrum revealed the formation of macromolecular-metal complex, indicating the strong coordination ability of tpy-pnipaam to metal. cloud point method and dynamic light scattering (dls) were used to characterize the thermosensitivity of tpy-pnipaam and macromolecular-metal complex. the results showed that the macromolecular-metal complex could self-assemble into nanoparticles in aqueous solution due to the amphiphilic property the macromolecular-metal complex solution showed a similar phase transition as pnipaam. in addition, the nanoparticles of the macromolecular-metal complex in aqueous solution were stable even at temperature above the lower critical solution temperature (lcst) due to electrostatic repulsion. this work indicated the great potentials of tpy-pnipaam as carriers for the delivery of therapeutic radioisotopes. |
