“…Thus, as the thickness of the adlayer increases, a decrease in k 0 app should be observed. The value of k 0 app for FeðCNÞ 4À=3À 6 at our uncoated gold samples is $10 À2 cm s À1 , which serves as a comparative baseline [102][103][104]. The rate constant is theoretically expected to decrease to $10 À6 cm s À1 at an electrode coated with a fully extended, closest-packed hexanethiolate layer.…”

“…Charge transport across nanoscopic molecular layers has been studied using a variety of experimental paradigms. [1][2][3][4][5][6] In contrast to studies using spectroscopic measurements of bridge-mediated donor/acceptor systems 5 or measurements of the redox kinetics at chemically modified electrodes, [7][8][9][10] a molecular electronic junction usually relies on direct electrodeto-molecule contacts to make a complete electronic circuit. 1,2,4,[11][12][13][14][15][16][17][18][19][20] The incorporation of a molecular component directly into a solid state device enables fundamental studies into the parameters that control charge transport across molecules and also opens several avenues in the quest for next-generation electronic devices.…”

“…The shape of cyclic voltammogram and current response at modified electrodes depend on a lot of variables such as the structural order and thickness of the SAM [37,[40][41][42], the size and chemical nature of probe molecules [43,44], and the solvent media containing monolayer and the probe molecules [43].…”
