Abstract

Ultraviolet photoemission spectra of the three-ring oligo(para-phenylene-ethynylene) and corresponding thiol were measured in the gas phase and compared to the spectrum of the thiolate chemisorbed on gold. The gas-phase spectra were simulated with valence effective Hamiltonian calculations, and these simulated spectra were used to assign the observed spectral features. The spectrum of the chemisorbed species was, apart from an overall shift, similar to that of the gas-phase species. These observations indicate that neither the thiol linker nor chemisorption significantly change the nature of the valence states of these molecules.
