Abstract

""The molecular structure and organization of self-assembled monolayers (SAMs) and multilayer films. grafted onto Au\\\/Si(1 1 1) surfaces of mononuclear transition metal dialkynyl bridged Pd(II) complexes. trans-[HS-Pd(PBu3)2-SH] (1), trans-[HS-Pd(PBu3)2(–C„C–C6H5)] (2) and of the binuclear complex trans,. trans-[HS-Pd(PBu3)2(–C„C–C6H4–C6H4–C„C–Pd(PBu3)2-SH] (3), have been investigated by extended.
