Photodynamic therapy(PDT)represents a promising method for the treatment of cancerous tumors.The success of PDT depends on the chemical and physical properties of the photosensitizer used.In this study,a novel photosensitizer,Chlorin-H [chlorin P6-13,15-N-(cyclohexyl)cycloimide] was synthesized,which displayed a characteristic long wavelength absorption peak at 698 nm.After 355 nm laser flash photolysis,the excited triplet states of Chlorin-H could react with O2 and 1O2 was produced,
