摘要：

The heterogeneous electron-transfer rate constants for Co(phen)3(2+/3+) and Fe(CN)6(4-/3-) at the bilayer lipid membrane (BLM) saturated with tetracyanoquinodimethane (TCNQ) were respectively (3 +/- 1) X 10(-4) and <2 X 10(-8) cm/s, determined by ac impedance spectroscopy. The large difference in the rate constants was explained by hydrophobic interaction between the interior of the BLM and the redox species, by the electrostatic interaction between the negatively-charged surface and the redox species in solution, and by the difference in formal potential between TCNQ and the redox species.
