在固相条件下合成了 4种四 (对 -羟基苯基 )卟啉稀土 ( Ln3+ =La3+ 、 Pr3+ 、 Nd3+ 、 Dy3+ )配合物 .用元素分析、 ICP、紫外可见光谱、红外光谱进行表征 ,并用循环伏安法研究了配合物的电化学性质 .实验结果表明 :稀土卟啉配合物的电化学性质相似 ,在循环伏安图中 ,出现了三对氧化还原峰 ,第一对为 [C44 H2 8N4O4Ln ( ) ]+ /[C44 H2 8N4O4Ln ( ) ],第二对为 [C44 H2 8N4O4Ln ( ) ]/[C44 H2 8N4O4Ln ( ) ]- ,第三对为 [C44 H2 8N4O4Ln ( ) ]- /[C44 H2 8N4O4Ln]

Four Terta(4-hydroxyphenyl)porphyrin rare earth elements complexes were synthesized by solid state reaction . The products were characterized by elemental analysis, ICP, UV, IR. The electrochemical behavior of complexes were investigated by cyclic voltammetry in DMSO. The results showed that the electrochemical behavior of rare earth elements complexes was similar. There were three redox peaks in the cyclic voltammetry of the complexes: 1 [C 44 H 28 N 4O 4Ln(Ⅲ)] + / [C 44 H 28 N 4O 4Ln(Ⅱ)],2 [C 44 H 28 N 4O 4Ln(Ⅱ)] / [C 44 H 28 N 4O 4Ln(Ⅰ)] -,3 [C 44 H 28 N 4O 4Ln(I)] -/ [C 44 H 28 N 4O 4Ln] 2- .
