Investigation of homogeneous photosensitized oxidation activities of palladium and platinum octasubstituted phthalocyanines: Oxidation of 4-nitrophenol

▶ Palladium and platinum phthalocyanines photocatalyse the transformation of 4-chlorophenol. ▶ Palladium-(dodecylthio)phthalocyanine giving the highest phototransformation quantum yield. ▶ The products of phototransformation are hydroquinone and 1,4-benzoquinone. ▶ Both type I and type II mechanisms are implicated in the phototransformation of 4-nitrophenol.
