Self-assembled monolayers of nitrile-functionalized alkanethiols on gold and silver substrates

Article Abstract:

Self-assembled monolayers (SAMs) formed from nitrile - functionalized alkanethiols (AT), NC(CH2)16SH (NC-C16), on (111) gold and silver substrates are characterized by X-ray photoelectron spectroscopy. Comparisons with previous data on CH3-terminated SAMs reveals that substitution of weakly interacting CH3 groups by the CN entities results in an increase in the average tilt angles of the alkyl chains.

Self-assembled monolayers of tetrathiafulvalene derivatives on Au(111): organization and electrical properties

Article Abstract:

The self-assembled monolayers (SAM) formed by tethering tetrathiafulvalene (TTF) derivatives through two thiolate groups directly to a gold surface are reported and the structural and electrical properties are studied. Based on the results, the dithiol variants would be ideal as candidate molecular wires in any self-assembled systems.

Structural forces in self-assembled monolayers: Terphenyl-substituted alkanethiols on noble metal substrates

Article Abstract:

The study evaluates the importance of the spatial orientation of the sulfur bonding orbitals for the structure and packing density in alkanethiolate self-assembled monolayers. The study concluded that self-assembled monolayers (SAMs) were to be well-defined, densely packed, and contamination free.
