Abstract
Poly(ethyleneglycol)-b-poly(4-vinylpyridine) (PEG-b-P4VP) and zinc meso-5,10,15,20-tetrakis-(4-sulfonatophenyl)porphyrin (ZnTPPS) form complex micelles based on electrostatic interactions. The complex micelles have a core-shell structure that can effectively prevent the demetallization and aggregation of ZnTPPS in acidic aqueous solutions (pH < 4.0).
摘要
聚（乙二醇）-b-聚（4-乙烯基吡啶）（PEG-b-P4VP）和锌 meso-5,10,15,20-四（4-磺酸钠基苯基）卟啉（ZnTPPS）基于静电相互作用形成复合胶束。该复合胶束具有核壳结构，可有效防止 ZnTPPS 在酸性水溶液（pH < 4.0）中脱金属和聚集。
