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 electrochemical behavior of Er, Co porphyrin complex ((TMOPP) Er [P (= O) (OEt) 2] 3Co (η5 C5H5) was studied and compared with that of the corresponding mononuclear complex The difference. The complex has four pairs of redox peaks in the CH2Cl2 solution, and the redox process is related to the central ion and the ligand of the complex respectively. When the complex modified glassy carbon electrode in NaClO4 solution, the same four pairs of redox peaks, but the peak position, shape, size and the former compared to the great changes have taken place. Further experiments show that the solution electrolyte concentration, pH, type and the thickness of the membrane on the modified electrode reaction behavior has an impact.
