Surface characterization reveals long-range order in rigid terphenyl thiolate adlayers on gold, suggesting structural models for molecular electronics.

Key Points

To comprehensively characterize the structural organization and packing of rigid-rod organothiolate self-assembled adlayers containing terphenyl backbones on Au(111) surfaces.
Synthesized and formed self-assembled monolayers of p-terphenylthiol (TPT) and p-terphenylmethanethiol (TPMT) on Au(111) substrates.
Evaluated surface periodicity and long-range structural order using low-energy electron diffraction (LEED).
Characterized chemical state, molecular orientation, and adlayer topography using X-ray photoelectron spectroscopy, infrared reflection-absorption spectroscopy, near-edge X-ray absorption fine structure, and scanning tunneling microscopy.
Low-energy electron diffraction confirmed the formation of long-range structural order for both TPT and TPMT adlayers on Au(111).
Multi-technique spectroscopic and microscopic characterization enabled the development of a comprehensive structural model defining molecular packing and orientation on the substrate.
