摘　　要：在固相条件下合成了 4种四 (对甲氧基苯基 )卟啉稀土 ( Ln=L a3+,Pr3+,Nd3+,Dy3+)配合物。用元素分析、ICP,UV及 IR光谱进行表征 ,用循环伏安法研究了它们的电化学性质。实验结果表明 :它们的电化学性质相似。在循环伏安图中出现了三对氧化还原峰。第一对为 [C4 8H36N4 O4 Ln( ) ]+/[C4 8H36N4 O4 Ln ( ) ],第二对为 [C4 8H36N4 O4 Ln ( ) ]/[C4 8H36N4 O4 Ln( ) ]-,第三对为 [C4 8H36N4 O4 L n( ) ]-/[C4 8H36N4 O4 Ln]2 -。Four tetra(4-methyoxyphenyl)porphyrin rare earth element complexes were synthesized by solide state reaction.The products were characterized by element analysis,ICP,UV,IR.The electrochemical behavior of the complexes was inverstigated by cyclic voltammetry in DMSO and the results showed similar electrochemical behavior. There were three inreversible peaks in the cyclic voltammetry of the complexes:(1) [C_48H_36N_4O_4Ln(Ⅲ)]+/[C_48H_36N_4O_4Ln(Ⅱ)];(2) [C_48H_36N_4O_4Ln(Ⅱ)]/[C_48H_36N_4O_4Ln(Ⅰ)]-;(3) [C_48H_36N_4O_4Ln(Ⅰ)]-/[C_48H_36N_4O_4Ln]2-.
