Abstract :
The process of self-assembling of thiophene oligomers on gold substrate was studied in situ by optical second harmonic generation (SHG). It is shown that for thiophene both molecular and adsorption-modified nonlinear optical susceptibility of the substrate contribute to the SHG field. On the base of simultaneous consideration of nonlinear-optical and two-channel Langmuir-like kinetic models kinetic parameters of adsorption/self-assembling are estimated.
