Abstract

Abstract: By using the method of ESR elimination of the spin of N-O radical,the photoinduced primary process of photosensitizer aluminum phthalocyanine (A1PCS)was studied.The results showed that the photoproduced anion radical of A1PCS was observed during the A1PCS photodynamic reaction in the presence of Pyrogallo or Cys under anoxic conditions, reflecting that the anion radicals may be another mechanism of A1PCS photosensitization besides the singlet oxygen.

Key words: Aluminum phthalocyanine, Anion radical, ESR
