Stability enhancement of ZnTPPS in acidic aqueous solutions by polymeric micelles

Chem Commun (Camb). 2010 Sep 21;46(35):6560-2. doi: 10.1039/c0cc01674h. Epub 2010 Aug 16.

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).
