Water soluble star polymer with zinc phthalocyanine core and PEG arms is presented.
The synthesis of zinc phthalocyanine end functional PEG is presented.
Photo-physicochemical behaviors of symmetrically PEGylated ZnPc are investigated.
Photo-physicochemical behaviors of asymmetrically PEGylated ZnPc are investigated.
Water soluble PEGylated ZnPc has high potential as photosensitizer in PDT treatment.
