卟啉诱导pH和温度双响应嵌段聚合物胶束化
Journal Title: Science Paper Online - Year 2009, Vol 4, Issue 3
Abstract
以偶氮二异丁腈(AIBN)为引发剂，异氰基丙基二硫代苯甲酸酯(CDPB)为链转移剂，通过可逆加成裂解链转移自由基(RAFT)聚合反应合成了具有温度和pH双重敏感窄分子量分布的聚甲基丙烯酸二甲基氨基乙酯(N,N-dimethylamino ethyl methacrylate，DMAEMA)与异丙基丙烯酰胺(N-isopropyl acrylamide NIPAM) (PDMAEMA-b-PNIPAM)全亲水性两嵌段聚合物，通过紫外光谱(UV-vis)，光子相关谱(DLS)，核磁共振(1H NMR)研究了加入5,10,15,20-四磺酸卟啉(TPPS)诱导PDMAEMA-b-PNIPAM嵌段聚合物的胶束化行为，结果表明，聚合物形成了以TPPS/DMAEMA为核，PNIPAM为壳的胶束，改变溶液温度，可以得到不同的聚集态结构。同时，由于嵌段聚合物与卟啉的相互作用，TPPS在不同的pH，可以分别形成H-聚集和J-聚集。
