The maximum absorption peak was at long wavelength (＞650nm), extinction coefficient achieves 10〓 degree, which was one degree higher than HpD. The study has revealed that CPD photosensitizer appeared blue movement under the relevant body environment. The spectra parameters provided basis for selecting light source of PDT. Measurement system which measured singlet oxygen and its quantum yields within the infare range had been set up and the quantum yields of singlet oxygen for CPD were reported: the quantum yields of singlet oxygen for CPD〓 was the highest (φ=0.83) while he quantum yields of singlet oxygen for CPD〓 was the lowest (φ=0.83). Photobleaching's half life time was studied.
