Katz, Eugenii published the artcileElectron transfer in self-assembled monolayers of N-methyl-N’-carboxyalkyl-4,4′-bipyridinium linked to gold electrodes, Computed Properties of 56523-59-2, the main research area is electron transfer methylcarboxyalkylbipyridinium gold electrode; cystamine bipyridine derivative electrode modification; chemisorption adsorption electrode modification; redox electrochem tunneling electrode modification; alkylbipyridinium modification kinetics electron transfer.
Electron transfer processes in monolayer assemblies formed by covalent linkage of N-methyl-N’-carboxyalkyl-4,4′-bipyridinium (1) to cystamine, chemisorbed onto Au electrodes, are examined The resulting monolayer exhibits nonordered structure being reflected by a similar rate constant to the bipyridinium redox sites, that is independent of the bridging alkyl chain length, ket = 550 s-1. The nonordered structure is also confirmed by the low electron transfer coefficients αa and αc, corresponding to 0.25 ± 0.05 and 0.3 ± 0.05, resp. By treatment of the nonordered monolayer assembly with 1-hexadecanethiol, C16SH, a more densely packed organized monolayer is formed, where the alkyl-substituted bipyridinium sites are stretched in the monolayer configuration. In these assemblies the electron transfer rate constants to the bipyridinium sites depend on the alkyl chain length bridging the redox site to the electrode. The electron transfer rate constants follow Marcus theory and the electron tunneling coefficient corresponds to β = 0.006 A-1.
