摘要: Four tetrathiol-terminated norbornane homologues were synthesized and self-assembled monolayers (SAMs) of these molecules formed on Au via adsorption from CH2Cl2. SAMs characterized structurally spectroscopic ellipsometry (SE), reflection−absorption infrared spectroscopy (RAIRS), Rutherford backscattering spectrometry (RBS), X-ray photoelectron (XPS). Results analyses show that the rigid norbornylogs form have a surface coverage slightly lower than alkanethiols, they exhibit nonmonotonic dependence film thickness molecular length. Nanoscale junctions incorporating electrically using conducting probe atomic force microscopy (CP-AFM). The resistances scale exponentially with contour length molecules, β = 0.9 A-1, consistent nonresonant tunneling mechanism. Further, resistance norbornyl correlates well ...
