Abstract
In this paper, the fluorescence spectra of porphyrinanthraquinone, por phyrin-anthraquinone Zn(I), and parent porphyrin were studied by means of fluorescence, The energy of singlet excited state (E-s), fluoresce nce quantum yield and quench percentage were estimated, It is demonstr ated by the data of fluorescence quench that the intramolecular electr on transfer, which leads to the formation of intramolecular electric c harge separating-state, occurred under excitation of light indeed. In the meantime, the effects of axial coordination and solvent on fluores cence property of PAQ compounds were studied.
