meso-四-(对甲氧基)苯基卟啉和meso-四-(对甲氧基)苯基锌卟啉的电化学性质
摘要:
合成了meso-四-(对甲氧基)苯基卟啉[T(p-OCH3)PP]及其锌配合物[ZnT(p-OCH3)PP],用核磁共振法对配合物进行了表征,用紫外可见光谱法,荧光光谱法及循环伏安法研究了配合物的光谱学和电化学性质;用多种电化学技术证明该配合物的峰电流为两电子转移的不可逆吸附波;用计时库仑法求得了单位分子的吸附量为1.41×10-10mol/cm2[T(p-OCH3)PP]和6.77×10-11mol/cm2[ZnT(p-OCH3)PP].对电极反应机理作了初步研究.

Synthesis and Electrochemical Property of the Zn-meso-tetrakis(p-methoxyl)phenylporphyrin
Abstract:
meso-Tetrakis(p-methoxyl)phenylporphyrin(T(p-OCH3)PP) and its Zn-complex (Zn-T(p-OCH3)PP) were synthesized and characterized by elemental analysis,1H NMR, UV and fluorescence spectra.The electrochemical properties of the complex have been investigated by cyclic voltammetry, electrocapillary method in DMSO and a tentative mechanism of reduction on the mercury electrode has been proposed.It is found that the peak currents of the complex are an irreversible adsorption wave.The adsorbed amount of T(p-OCH3)PP and Zn T(p-OCH3)PP on mercury electrode surface were 1.41×10-10 and 6.77×10-11 mol/cm2, respectively as determined by chronoculometry.
