Abstract: “The template approach” was used for the synthesis of eight metal phthalocyanine complexes containing piperidine group(PEO)4PcM, where M=Zn, Ni, Co, Cu, PEO=2-(piperidin-1-yl) ethyoxyl. These complexes were characterized by FTIR, mass spectrum, elemental analysis and so on. The UV-Vis absorption spectra, fluorescence emission spectra and capacity of photo-generating singlet oxygen were examined. The results showed that two zinc phthalocyanine complexes possessed high molar extinction coefficient, fluorescence quantum yield, high rate of photo-generating singlet oxygen. The complex with formula β-(PEO)4PcZn had a photoinhibition effect to BEL7402 liver cancer cells up to 83% in case that the irradiation with 670 nm laser light(dosage 1.2 J) and the concentration of β-(PEO)4PcZn with 10 μmol/L were used.
