Abstract: A histidine-linked porphyrin (1) and its lanthan on complexes[Ln=Sm(2), Eu(3), Er(4), Dy(5), Yb(6)] were prepared, purified and characterized by UV-Vis spectra. The correlation between the structures of the complexes and their UV spectra, IR spectra, elemental analysis and mass spectra were discussed and their specific spectra were explained. The fluorescence intensity and the quantum yield of porphyrin 1 were low because of the electron withdrawing group on peripheral porphyrin ring. The fluorescence intensity and the quantum yield of lanthanon metalloporphyrins 2-6 were much more different because of the property of lanthanon ions and intensity of the radiationless transition. Surface photovoltage spectra of porphyrins 1 and complexes 2-6 were influenced by the property of external electric field and intensity of external voltage.
