[Fluorescence spectra and photo-generating rate of singlet oxygen of phthalocyaninatopalladium].
The absorption spectral properties, fluorescence spectral properties and the abilities of photo-generating singlet oxygen of four phthalocyanines, namely tetra-alpha-(2,2,4-trimethyl-3-pentoxy) phthalocyaninatopalladium (zinc) and tetra-alpha-(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.
