摘要
The molecular structure of organometallic polymer Pt-DEBP [-Pt-4PBu(3))(2)-C C-C12H8-C C-](n), has been investigated by X-ray absorption spectroscopy (XAS). Data collected at the Pt-L-III edge of Pt-DEBP thick films spin-deposited onto Cr/Si(111) and Au/Si(111) substrates, have been analyzed to achieve information about the geometrical arrangement of the acetylene moieties and of the tributyl phosphine groups around the transition metal. The hypothesised square planar configuration of the ligands around the transition metal has been confirmed. From the comparison between the atomic distances in the pellet reference sample and in the film samples the self-assembling behaviour of the rod-like organometallic polymer, attributed to the predominant intermolecular forces, has been confirmed.
