• this reason, we give some detailed information on its synthesis. Owing to the air sensitivity of aliphatic selenols, we did not try to synthesize the selenol Trp1SeH but aimed for a related, protected compound. Since the diselenide (Trp1Se)2 is rather insoluble, we decided to turn it into the

CV, XPS and ultraviolet photoemission spectroscopy (UPS) measurements of their monolayers on a gold surface were investigated and the results were compared with those obtained from the thiol-terminated

Furthermore, a comparative UPS study of the gold–thiol and gold–selenol tripodal interfaces showed that the charge

In the latter case, S–C bond scission occurs, leading to the opening of the ring and observation of thiolate species [52][53][54][55][56][57][58][59][60][61][62][63]. The loss
