Self-assembled monolayers of aromatic selenolates on noble metal substrates

Article Abstract:

High-resolution X-ray photoelectron spectroscopy is used to characterize the self-assembled monolayers (SAMs) formed from bis(biphenyl-4-yl) diselenide (BBPDSe) on Au(111) and Ag(111) substrates. The results show that the film quality of the biphenyl selenolate (BPSe) SAMs is superior to their thiol analogues.
