摘要: 合成了1,3,5,7-四甲基-2,4,6,8-四乙基卟啉(TMTEP)及其钯络合物(PdTMTEP),并利用表面光电压谱(SPS)和场诱导表面光电压谱(FISPS)技术对它们的表面光伏特性进行了研究.TMTEP有较强的荧光发射,而PdTMTEP以磷光辐射为主,其光伏响应强度比TMTEP的强得多;在外电场诱导下,PdTMTEP的Soret带与Q带的光伏响应强度随外加正电场光伏响应强度的增加而增强,随外加负电场光伏响应强度的增加而减弱,并且在680,750nm处出现两个新的光伏响应带,这两个光伏响应带与极化子跃迁有关.

Abstract: The surface photovoltaic properties of tetramethyltetraethyl porphyrin(TMTEP) and palladium tetramethyltetraethyl porphyrin(PdTMTEP), which was synthesized by using improving technique, was studied by surface photovoltage spectra(SPS) and field induced surface photovoltage spectra(FISPS). The photovoltaic response intensity of PdTMTEPis much stronger than that of TMTEPsince PdTMTEP shows a strong phosphorescence and weak fluorescence. The photovoltaic response intensity of Soret band and Q band for PdTMTEP are enhanced with an external positive electric field and weakened with a negative electric field. Moreover, two new photovoltaic response bands appear at 680 and 750 nm, which are related to the transition of polaron.

Key words: Palladium tetramethyltetraethyl porphyrin, Surface photovoltaic spectroscopy, Field induced surface photovoltage spectroscopy
