    • The advancing contact angle of water on the surface of the SAM of the interchain anhydride was stable during the measurement. The half-life time for hydrolysis of acetic anhydride in water is about 6 min (Wolfenden, R.; Williams, R. J. Am. Chem. Soc. 1985, 107, 4345-4346). We hypothesize that the hydrolysis of the interchain anhydride is slower on the surface than in solution because the surface has a lower dielectric constant than water.

    • The positions of these shoulders were determined by subtracting the spectrum of the interchain anhydride from that of the mixed SAM of carboxylic acids and 11-undecylamides. Although subtraction of reference spectra has no mathematical justification, it allowed us to estimate the position of these shoulders.

    • A lower yield of this transformation would result in a smaller amount of the interchain anhydride groups and subsequently a lower surface density of the hydrocarbon layer.
