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 rare earth (Ln = L a3 +, Pr3 +, Nd3 +, Dy3 +) complexes of tetrakis (p-methoxyphenyl) porphyrin were synthesized under solid state conditions. The elemental analysis, ICP, UV and IR spectra were used to characterize their electrochemical properties by cyclic voltammetry. The experimental results show that: their electrochemical properties are similar. Three pairs of redox peaks appeared in the cyclic voltammogram. The first pair is [C4 8H36N4 O4 Ln ()] / [C4 8H36N4 O4 Ln ()], the second pair is [C4 8H36N4 O4 Ln ()] / [C4 8H36N4 O4 Ln [C4 8H36N4 O4 L n ()] - / [C4 8H36N4 O4 Ln] 2 -.
