应用循环伏安法、微分脉冲伏安法、紫外-可见和荧光光谱研究了一种新型钌化卟啉[Ru(phen)2(MPyTMPP)Cl]+(phen=1,10-邻菲咯啉,MPyTMPP=5-(3-吡啶)-10,15,20-三-(4-甲苯基)-卟啉)在多壁碳纳米管(MWCNTs)修饰的玻碳(GC)电极表面的电化学特性及其与电极上和溶液中双十六烷基磷酸盐(DHP)的作用.结果表明:[Ru(phen)2(MPyTMPP)Cl]+能强吸附在MWCNTs-DHP/GC电极表面,并呈现一对由表面过程控制的氧化还原峰;适量DHP有利于该配合物的吸附固定;[Ru(phen)2(MPyTMPP)Cl]+能与溶液中的DHP形成结合体,导致配合物中心离子反应电位负移.
A new type of ruthenium porphyrin [Ru (phen) 2 (MPyTMPP) Cl] + (phen = 1,10-phenanthroline) was investigated by cyclic voltammetry, differential pulse voltammetry, UV-Vis and fluorescence spectroscopy. , Electrochemistry of MPyTMPP = 5- (3-Pyridyl) -10,15,20-tris- (4-tolyl) -porphyrin) on Multi-walled Carbon Nanotubes The results showed that [Ru (phen) 2 (MPyTMPP) Cl] + could adsorb strongly on the surface of MWCNTs-DHP / GC electrode and (Pheny) 2 (MPyTMPP) Cl] + can form a conjugate with DHP in solution, resulting in the formation of a complex center ion Negative shift reaction potential.
