Abstract

We report on a vibrational study of the self-assembly of para-nitroanilino-dodecane-thiol (p-NAT, NO₂-C₆H₄-NH-(CH₂)₁₂-SH) molecules on polycrystalline gold surfaces, by means of sum-frequency generation (SFG). In the investigated spectral range (1150 to 1400 cm^-1), the evolution of the vibrational fingerprint indicates that important reorientations of the molecules occur during film growth, until a stable conformation is reached slightly before saturation coverage. The experimental data are interpreted with the help of ab initio calculations from which the geometrical orientation of the self-assembled molecules can be deduced.
