Abstract: The surface photovoltaic properties of TPP and its p-phenylsubstituted derivatives as well as metallo derivatives were studied by surface photovoltage spectroscopy(SPS). The results showed that the p-phenylsubstituted groups (-NH2-N(CH3)2,-N+ (CH3)3I-) in different degree influenced the surface photovoltaic properties of porphyrins.For-N+(CH3)3I- substituted tetraphenylporphine particularly,the B band in SPS spectra was splitted into two reverse symbolic peaks:-400nm and 469nm. of metalloporpbyrines with FeCl2+,Co2+,Ni2+, Cu2+, and Zn2+, only CuTPP and ZnTPP have the surface photovoltaic property.
Key words: surface photovoltage spectroscopy, surface photovoltaic property, tetraphenylporphrine
