    • 17SH) and the terminal methyl groups on the exchanging ligand (Scheme 2) and both will contribute to the value for the integration of the methyl resonance (0.88 ppm). (Note: In some cases, the terminal methyl group on the photoactive ligand had a slightly different chemical shift than the base ligand, but nonetheless, the entire triplet was integrated in order to determine the stoichiometry.) Here, it is necessary to subtract the integrated value for the three protons associated with the terminal methyl group on 2, 3, 4, or 5 from the total value for the integration of the triplet at 0.88 ppm. When this is done, we account for the integration for the terminal methyl group on the exchanging ligand and what remains is the integration for the methyl group from the original hexanethiolate, dodecanethiolate, or octadecanethiolate ligand. When this is known, the stoichiometry of the exchanged colloid can be determined.

    • The number of defect sites was calculated by assuming that all of surface atoms at either the edge or the vertice and those directly adjacent to the edge or vertice can bind a probe substrate.
