Abstract
Electrochemical properties of a novel monoruthenated porphyrin [Ru(phen)2(MPyTMPP)Cl]+ (where phen =1,10-phenanthroline,MPyTMPP =5-(3-pyridyl)-10,15,20-tris-(4-methylphenyl) porphyrin) on a multi-walled carbon nanotubes (MWCNTs) modified glassy carbon (GC) electrode with the participation of dihexadecyl phosphate (DHP) have been investigated by using cyclic voltammetry,differential pulse voltammetry,UV-Visible spectroscopy and fluorescence spectroscopy. It is found that [Ru(phen)2(MPyTMPP)Cl]+ has the ability to adsorb strongly onto the MWCNTs-DHP modified GC electrode and exhibits a pair of redox waves controlled by surface electrochemical process. DHP dispersed on the MWCNTs/GC electrode can facilitate the ruthenium complex to adsorb onto the MWCNTs-DHP surface. A new complex is generated by the interaction of [Ru(phen)2(MPyTMPP)Cl]+ on the modified electrode with DHP in buffer solution and its formal potential corresponding to the Ru(III)/Ru(II) reaction indicates an negative shift.
