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[1]。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、光MOS晶体管等的应用前景是分不开的[2]。Dahlberg等[3]曾将各种金属酞善的表面光伏性质与它们的能级结构建立联系。本文对四苯基外琳及其衍生物的表面光电压谱[4]进行了系统考察,探讨外琳环上取代基和中心金属离子及其分子间相互作用的改变与光伏性质的关系。

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
