Organic thin films prepared from long-chain organothiols
have been self-assembled on gold surfaces and their chemistry
and structural properties studied by physical, electrochemical
and spectroscopic methods. The mechanism of charge transfer
across these organic thin films was of particular interest and
was studied by combined spectroscopic and electrochelllical
methods. The influences of chain length, terminal functional
group I and sol vent on the electrochemical kinetics were
studied. Evidence of a kinetic barrier to charge transfer
pointed to a charge-diffusion mechanism across the organic
thin films. An Infrared Reflection-Absorption Spectroscopy
(IRRAS) method was developed to monitor the titration of acid
functionalized films. The method compared favorably with the
currently-used goniometry method because the IRRAS method was
faster, less prone to operator bias, and provided structural
