abstract = {4-Methyl-4'-(n-mercaptoalkyl)biphenyl
(CH3-C6H4-C6H4-(CH2)(n)-SH, n = 1-6, BPn) monolayers
self-assembled on Au(111)-(1 x 1) electrode surfaces were
studied by scanning tunneling microscopy, cyclic
voltammetry, and chronoamperometry. Distinct odd-even
effects were found for the adlayer structures, the
interfacial adlayer capacitances, as well as for the
potentials and charges of reductive and oxidative
desorption. The potential of zero charge, E-pzc, of
BPn-modified gold electrodes was estimated by a controlled
immersion technique in hanging meniscus configuration to
E-pzc = -(0.30 +/- 0.05) V, rather independent of the length
of the alkyl spacer. The reductive desorption of BP3 and BP4
adlayers were quantitatively described by models based on
hole nucleation and growth mechanisms, such as the
exponential law of one-step hole nucleation (BP3), or hole
nucleation according to a.power law (BP3, BP4) in
combination with a linear law of growth. No odd-even
characteristics were found for the kinetic currents of the
Fe(CN)(6)(4-)/Fe(CN)(6)(3-) redox reaction in the presence
of BPn's. For the dependence on alkyl chain length, a
structure sensitive attenuation parameter beta = (11.5 +/-
1.0) nm(-1) was derived, which is interpreted according to a
"through-bond" tunneling mechanism.},
