    • Compound 1 was prepared by the formation of the α-thiolacetate γ-thioltert-butoxycarbonyl. The latter was removed with TFA without disruption of the thiolacetate. A manuscript (Flatt, A. K.; Yao, Y.; Maya, F.; Tour, J. M.) is in preparation detailing this orthogonal deprotection approach.

    • This was further verified by the assembly of 1 on a surface of freshly deposited Au (on Cr/Si) for 24 h, in the absence and presence of polycarbonate, and checking by ellipsometry after rinsing the surface well. Ellipsometric thicknesses were consistent with near-monolayer formation of 1: 2.8 ± 0.25 nm in the absence of polycarbonate (calcd 2.5 nm excluding the tilt15 from the surface normal) and 3.1 ± 0.25 nm in the presence of polycarbonate. Therefore, as expected,14 polycarbonate did not affect the SAM formation; however, a small amount of multilayer formation was occurring, presumably due to loss of the acetate and disulfide formation over the prolonged assembly time.15

    • Compound 2 has been prepared previously. See Bain, C. D.; Troughton, E. B.; Tao, Y.-T.; Evall, J.; Whitesides, G. M.; Nuzzo, R. G. J. Am. Chem. Soc. 1989, 111, 321. Note that 2 is ∼1 Å shorter in length than 1; however, the effective length of 2 will be ∼3-4 Å shorter since alkanethiols have ∼33° tilt from the surface normal (resulting in 1.8 nm Au-to-acetate distance) while the OPEs have <20° tilt.15

    • There may have been adventitious airborne molecules assembled between the metallic islands; however, we always treated the chips with UV ozone prior to use. Therefore, their presence is unlikely to be a significant factor.
