摘　　要：合成2种在苯环对位连接性质不同取代基的卟啉单体和4种桥联基团性质各异的卟啉低聚物,并利用循环伏安法研究上述卟啉单体和卟啉低聚物的电化学性质.结果表明:卟啉单体周边连接推电子取代基与连接吸电子取代基的卟啉单体相比电极电势正移;比较卟啉低聚物电化学性质发现,桥连基团的性质及整个卟啉分子的共轭程度对其电化学性质均有不同程度的影响.The authors synthesized two porphyrin monomers with different substituents and four porphyrin oligomers with different bridge-linked reagents according to the literatures.The electrochemical properties of the porphyrins were studied by using cyclic voltammetry（CV） and compared with those of other porphyrin molecules under similar experimental conditions.It was found that porphyrin monomer linked with an electron-donating group was easy to reduce.The electrochemical properties of porphyrin oligomers were influenced by bridge-linked reagents and conjugative effect of porphyrin molecules.
