Sum frequency spectroscopy of Langmuir-Blodgett fatty acid films on hydrophobic gold

Article Abstract:

Langmuir-Blodgett multilayer films of cadmium salts of fatty acids deposited onto hydrophobic gold surfaces have been found to be sum frequency active in the C-H stretching region is discussed. These findings imply that interpretation of SF spectra of LB multilayer films deposited on metal substrates must be performed with care and that deconvolution of spectra in terms of contributing layers is imperative.

Long-range heterogeneous electron transfer between ferrocene and gold mediated by n-alkane and N-alkyl-carboxamide bridges

Article Abstract:

Electron-transfer rates between ferrocene and gold are measured for two series of ferrocene-based alkanethiolate monolayers on gold electrodes. Monolayers are studied using a novel ac voltammetry method to measure the standard electron-transfer rate constants for oxidation/reduction of the ferrocene groups.
