中文摘要：

合成了尾式氨基酸卟啉5-（三苯甲基-组氨酸酰胺基苯基）-10，15，20-三苯基卟啉（1）的稀土金属配合物[Ln=Sm（2），Eu（3），Er（4），Dy（5），Yh（6）]．通过紫外-可见光谱、红外光谱、元素分析及飞行时间质谱对稀土金属卟啉配合物进行了表征，并研究了卟啉样品的荧光性质和表面光电压性质．由于卟啉1周边存在吸电子基团，致使其荧光发射强度和荧光量子产率较低；稀土金属卟啉配合物3的荧光量子产率较高，配合物6的荧光量子产率最低，这主要是由稀土金属离子性质及无辐射跃迁强度不同造成的．通过研究卟啉样品的表面光电压性质发现，外加电场性质及外加电压强弱对光电压信号有较明显的影响，这为氨基酸类金属卟啉化合物在光电器件方面的研究提供了一定的理论依据．

英文摘要：

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 in- tensity 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 photovohage spectra of porphyrins 1 and complexes 2--6 were influenced by the property of external electric field and intensity of external voltage.
