摘　　要：利用醋酸锶与四苯基卟啉反应,合成了四苯基卟啉锶配合物。利用元素分析、红外、核磁共振等对该配合物进行了结构表征。采用紫外-可见吸收光谱、荧光光谱和循环伏安法研究了该配合物的光电性能。四苯基卟啉锶配合物紫外-可见吸收光谱有一个强的吸收峰和一个次强的吸收峰,分别为428、457 nm。荧光光谱有一个强的发射峰和一个弱的发射峰,分别为610、676 nm。循环伏安法测得其氧化峰电位为1.558 V和1.051 V。与四苯基卟啉相比,四苯基卟啉锶紫外吸收发生红移,而荧光发射发生蓝移。The reaction of tetraphenylporphyrin and strontium acetate was used for synthesizing the complex tetrakis （phenyl） porphyrin strontium Sr（TPP） 2. The structure of Sr（TPP） 2 was determined by elemental analyses, FTIR and ^1HNMR. Its UV-Vis absorption spectrum, fluorescence spectrum and cyclic vohammetry were studied for photoelectric properties. In the UV-Vis absorption spectra of Sr（TPP）2, there are one strong absorption peak at 428 nm and one weak absorption peak at 457 nm. Sr（TPP）2 emits the fluorescence with one strong peak at 610 nm and one weak peak at 676 nm. In contrast to tetraphenylporphyrin, the UV-Vis absorption peak of Sr（TPP）2 is of red-shift and the fluorescence peak is of blue-shift.
