Christopher D. Zangmeister, Roger D. van Zee, Steven W. Robey, N E. Gruhn, Yuxing Yao, J M. Tour
Photoemission spectra of para-phenylene-ethynylene thiols chemisorbed on gold have been measured. Four compounds were studied: 4,4'-bis(phenylethynyl)-benzenethiol, 4 (phenylethynyl)benzenethiol, 4-ethynylbenzenethiol, and benzenethiol. The spectra were

Energy-Level Alignment and Work Function Shifts for Thiol-Bound Monolayers of Conjugated Molecules Self-Assembled on Ag, Cu, Au, and Pt

Christopher D. Zangmeister, Laura B. Picraux, Roger D. van Zee, Yuxing Yao, J M. Tour
Photoemission spectra have been used to determine the energy-level alignment and work function of monolayers of 4,4'-bis-(phenylethynyl)benzenethiol, 2 naphthalene thiol, and 3-(naphthalen-2-yl)propane-1-thiol self-assembled on Ag, Cu, Au, and Pt. For each

Fermi Level Alignment and Electronic Levels in Molecular Wire Self-Assembled Monolayers on Au

Christopher D. Zangmeister, Steven W. Robey, Roger D. van Zee, Yuxing Yao, J M. Tour
A combination of one- and two-photon photoelectron spectroscopies are used to determine the electronic structure around the Fermi level for self-assembled monolayers of a prototypical molecular wire , 4,4 -(ethynylphenyl)-1-benzenethiol (C6H5-C≡C-C6H4-C≡C-

Structure and Chemical Characterization of Self-Assembled Mono-Fluoro-Substituted Oligo(phenylene-ethynlyene) Monolayers on Gold

Monolayers of oligo(phenylene-ethynylene) (OPE) molecules have exhibited promise in molecular electronic test structures. This paper discusses films formed from novel molecules within this class, 2-fluoro-4-phenylethynyl-1-[(4-acetylthio)-phenylethynyl

Valence Electron Orbitals of an Oligo(p-phenylene-ethynylene)thiol on Gold

March 1, 2004
Author(s)
Christopher D. Zangmeister, Steven W. Robey, Roger D. van Zee, Yuxing Yao, J M. Tour
One- and two-photon photoemission spectra have been measured for monolayers of oligo(para-phenylene-ethynylene) thiolate chemisorbed on gold surfaces. Within 5 eV of the Fermi level, four states are observed, two occupied (2.0 eV and 4.0 eV below the Fermi
