Abstract
Mixed monolayers containing an electroactive thiol, HS(CH2)(15)CONHCH( 2)pyRu(NH3)(5)(2+/3+), and a diluent thiol, HS(CH2)(15)COOH, on gold e lectrodes are examined in acetonitrile electrolyte (0.1 M LiClO4) as a function of overpotential and temperature. Kinetic and thermodynamic parameters from ca. -45 to +20 degrees C are obtained by cyclic voltam metry and chronoamperometry. Reorganization energies obtained from Taf el plots and Arrhenius plots both yield a reorganization energy of 0.8 eV for the redox centers.
