    • We chose NaF as a supporting electrolyte due to the weak interaction between the fluoride ion and gold (Dickinson, K. M.; et al. Electrochim. Acta 1992, 37, 139-141) that should not inhibit formation of the SAM.

    • note
    • The concentration of effective micelles near the interface is not likely zero for long times after the adsorption has begun due to a decreasing adsorption rate of alkanethiols as surface sites become occupied (refer to eq 18).

    • Equation 18 is similar to that used by Rahn and Hallock (Langmuir 1995, 11, 650-654). We have added the exponent x to allow for a more complex dependence of coverage on rate.

    • note
    • The use of eq 21 in conjunction with either eq 22 or 23 represents a single-parameter model for describing the kinetics of SAM formation from alkanethiol-containing aqueous micellar solutions. We also developed a model that contains rate constants for both release and adsorption (two-parameter model). While the two-parameter model did provide satisfactory fits to the coverage data (perhaps due to the presence of a second adjustable parameter), the resulting rate constants determined from this fitting were physically unrealistic. The single-parameter model used herein represents a good approximation of the kinetics for the diffusion-limited case.

    • note
    • 6 concentration studied (30 mM), and given a 1 mM alkanethiol concentration, the micelles contain an average of ∼10 alkanethiols. This average is based on the assumption that the aggregation number of the micelles is identical to that in the absence of thiols as reported in Table 1.
