Abstract: During the course of our investigation of the electron
transfer properties of some redox species through highly
hydrophobic long chain alkanethiol molecules on gold in aqueous
and nonaqueous solvents, we obtained some intriguing results
such as unusually low interfacial capacitance, very high values
of impedance and film resistance, all of which pointed to the
possible existence of a nanometer size interfacial gap between
the hydrophobic monolayer and aqueous electrolyte. We explain
this phenom
