Abstract：The absorption spectral properties, fluorescence spectral properties and the abilities of photo-generating singlet oxygen of four phthalocyanines, namely tetra-α-(2,2,4-trimethyl-3-pentoxy) phthalocyaninatopalladium (zinc) and tetra-α-(2,4-diterbutylphenoxy) phthalocyaninatopalladium (zinc), were determined. Experimental results show that the ability of photo-generating singlet oxygen of phthalocyaninatopalladium is similar to that of phthalocyaninatozincx, though palladium(Ⅱ) is an open shell electron structure and zinc(Ⅱ) is a closed shell structure. This may be concerned with a weak flourescence intensity and a strong inter-crossing transition of phthalocyaninatopalladium.
