摘要：
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).
