Fabrication of thiol-surfaces using aromatic self-assembled monolayers

Article Abstract:

Self-assembled monolayers (SAMs) formed from [1,1'-biphenyl]-4,4'-dimethanethiol and [1,1';4',1"-terphenyl]-4,4" -dimethanethiol on Au are characterized by X-ray photoelectron spectroscopy (XPS), high-resolution XPS, infrared reflection absorption spectroscopy and other measurements. The aromatic dithiols are well suited for the fabrication of thiol-terminated SAMs.

Self-assembly of n-alkanethiols: a kinetic study by second harmonic generation

Article Abstract:

The mechanism of self-assembly of n-alkanethiols adsorbing on polycrystalline gold has been investigated in situ and in real time under various experimental conditions. Specifically, the chain length of the thiols and the influence of the thiol concentration in different solvents were studied. Results show that the thiolate formation of n-alkanethiols can be elucidated best by a kinetic model which identifies the displacement of solvent molecules that are adsorbed on the substrate and/or incorporation of alkanethiols into thiolate islands as the rate limiting steps.
