- 中文摘要: Silicon phthalocyanines and silicon naphthalocyanines, which are two derivatives in the family of hematoporphyrin, have been synthesized to assess their potential as photosensitizers for photodynamic therapy. For these complexes the red shift of their Q-band maximum absorption tends to depend on the nature of the axial substituent. The bimolecular rate coefficients for the interacting between photosensitizer, either SiNC or SiPC, and generated singlet molecular oxygen were determined from the time-resolved emission spectrum of singlet oxygen at 1.27.mu.m. On the basis of these data the electron-transfer quenching mechanism is discussed in relation to the Marcus model.
