| Metallopolymers have attracted more and more attention because of their unexpected and remarkable properties.Carbolong complexes are a new family of Mobius metalla-aromatic complexes with various unique properties,including nearinfrared photothermal conversion effects.Thermally responsive polymers are a kind of polymers that can respond to the stimulation of temperature change.The purpose of this thesis is to introduce the photothermal conversion properties of carbolong complexes into thermally responsive polymers to prepare the unique near-infrared photothermal responsive metallopolymers.The first chapter is the introduction,which mainly introduces the relevant research background of this thesis,including the introduction of 12-carbolong complexes,metallopolymers,near-infrared absorbent materials,and thermally responsive polymers.In chapter 2,we synthesized a multifunctional star-shaped metallopolymer based on poly(N-isopropylacrylamide)(PNIPAM)by using 12-carbolong complex as a light heat source.This polymer has excellent near-infrared photothermal effect and exhibits rapid stimulus response under near-infrared light irradiation.It is a new smart polymer material with dual thermal response and light response effect.In chapter 3,we synthesized 12-carbolong complex with polymerization activity by means of chemical modification,and successfully prepared metal-containing polymer hydrogel PNIPAM/Os based on PNIPAM through chemical covalent crosslinking using it as a cross-linking agent.The hydrogel has excellent photothermal properties and shows remarkable heating effect under near infrared laser irradiation.Moreover,the hydrogel has a completely repeatable and reversible phase transition behavior,which can be excited by near-infrared light irradiation.And we demonstrate that the hydrogel can be used as a remote laser operated liquid microvalve.In chapter 4,we summarize and look forward to all the work. |
