dc.description.abstractPhotosensitized oxidation of 4-nitrophenol was studied in organic solutions with seven octasubsti￾tuted thio and aryloxy palladium and platinum phthalocyanines acting as photosensitizers. Kinetic studies conducted also showed that the complexes have different singlet oxygen quenching con￾stants with direct implication on the quantum yield of photodegradation of 4-nitrophenol (˚4-NP). Palladium analogues gave better results than the platinum analogues in terms of ˚4-NP with palladium- (dodecylthio)phthalocyanine giving the highest yield of 1.8 × 10−3. Gas chromatography (GC) and liquid chromatography connected to a mass spectrometer (LC–MS) were used to confirm the photodegradation products which were hydroquinone and 1,4-benzoquinone.en_US
