Probing the surface molecular structure in the UPS spectra of octadecanethiol and 1-cyclohexyl-12-dodecanethiol self-assembled on gold

摘要

UPS studies of monolayers of octadecanethiol and 1-cyclohexyl-12-dodecanethiol chains self-assembled on gold evidence the fact that molecular structure fingerprints can be detected in the outer valence region. The results provide incentive for a more systematic use of UPS toward this goal in conjunction with other surface sensitive techniques and quantum chemistry calculations.
