中文摘要 | the electrochemical behavior of the electroactive self-assembled monolayers (sams) of thiol-functionalized viologen, ch3(ch2)(9)v2+(ch2)(8)sh, where v2+ is a viologen group, on the gold electrodes is examined by cyclic voltammetry and electrochemical a.c. impedance. a monolayer of viologen is immobilized on the gold electrode surface via the au-s bond and the normal potentials corresponding to the two successive one-electron transfer processes of the viologen active centers are -310 mv and -652 mv (vs. ag/agcl) in 0.1 mol l(-1) phosphate buffer solution (ph 6.96) respectively. these results suggest that the viologen sams are stable and well-behaved monolayers. the experimental impedance data corresponding to different forms of viologen group have been fitted to equivalent electrical circuits, and the surface capacitances and resistances have been given. the heterogenous electron transfer rates of the first and the second redox processes are 7.57 s(-1) and 1.49 s(-1) respectively through a.c. impedance. |
