The new tetrakis-(6-oxyquinoline)phthalocyaninato zinc (II) (5), octakis-(6-oxyquinoline)phthalocyaninato zinc (II) (6) and their quaternized derivatives (5a and 6a) have been synthesized and characterized. Photophysical and photochemical properties of 6-oxyquinoline appended zinc (II) phthalocyanines are investigated in dimethylsulfoxide (DMSO) for both the non-ionic (5 and 6) and quaternized ionic
