The synthesis of novel directly conjugated zinc(II) phthalocyanine via palladium-catalyzed Suzuki-Miyaura cross-coupling reaction and its quaternized water-soluble derivative: Investigation of photophysical and photochemical properties

The novel zinc(II) phthalocyanine directly conjugated with 4-(diethylamino)phenyl groups via CC bond formation using Suzuki-Miyaura coupling reaction was synthesized for the first time. This phthalocyanine was converted to the quaternized derivative to enhance water solubility and promising as photosensitizer for photodynamic therapy.
