摘　　要：酞菁和卟啉染料是一类典型的分子半导体材料,由于其在生命过程、癌的治疗等生物学上的探索及其化学传感、光电特性在固体电子学器件研究中占有很重要的地位。尤以这类染料的光电性质深受人们的重视,这与太阳能光电池。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 (-NH_2-N(CH_3)_2,-N^+ (CH_3)_3I^-) in different degree influenced the surface photovoltaic properties of porphyrins.For-N^+(CH_3)_3I^- substituted tetraphenylporphine particularly,the B band in SPS spectra was splitted into two reverse symbolic peaks:-400nm and 469nm. of metalloporpbyrines with FeCl^(2+),Co_(2+),Ni^(2+), Cu^(2+), and Zn^(2+), only CuTPP and ZnTPP have the surface photovoltaic property
