摘要
研究了Er,Co 卟啉配合物((TMOPP)Er[P(=O)(OEt)2]3Co(η5 C5H5))的电化学行为,并比较了它与相应的单核配合物电化学行为的差异。该配合物在CH2Cl2溶液中有四对氧化还原峰,其氧化还原过程分别与配合物的中心离子和配体有关。而当该配合物修饰的玻碳电极于NaClO4溶液中时,同样出现四对氧化还原峰,但是峰的位置、形状、大小与前者比较发生了很大的变化。进一步实验又表明,溶液的电解质浓度、酸碱性、种类以及膜的厚度等对修饰电极的反应行为都产生影响。
The voltammetric behavior of (TMOPP)Er[P(=O)(OEt)_2]_3 Co(η~5-C_5H_5) complex was investigated in different condition. Four pair of the oxidation -reduction peaks are present with E_(1/2) about at (+0.566), +0.852 , +1.070 and +1.371 V in CH_2Cl_2 solution, respectively. While this complex modified on the glassy carbon electrode, four pair of peaks can also be found in 0.1 mol·L^(-1) NaClO_4. But its behavior is greatly different from that of it in CH_2Cl_2 solution. And it is also greatly affected by the concentration of NaClO_4 solution, the value of pH, the type of supporting electrolytes, and the thickness of the modified film.
