“…Instead of the widely used trialkylphosphine auxiliary ligands on the group 10 metals, the synthesis of a new Pt complex trans-Pt(PPh 2 Fc) 2 Cl 2 (Fc ¼ ferrocenyl) was established which then afforded a soluble pale-yellow platinum polyyne 3 through the Sonogashira-type reaction with 1,4-diethynyl-2,5-dioctyloxybenzene (Scheme 2).

This review article surveys the electronic and photophysical properties of conjugated organometallic polymers built upon the title compound and its related derivatives focussing primarily on systems investigated in our laboratories. The general structure of the polymers is (trans-bis(para-ethynylbenzene)bis(phosphine)platinum(II)-G)(n) where G is a conjugated group such as thiophene, fluorene, carbazole, substituted silole, quinone derivative, and metalloporphyrin residue, or a non-conjugated main-group moiety. Systems based on substituted phenylene units and other related fused rings are also discussed. The phosphine ligands are generally triethyl- or tri-n-butylphosphine groups. These trans-platinum(II) polymers and the corresponding model compounds are compared to the corresponding ortho-derivatives in the quinone series, and the newly prepared paracyclophane-containing polymers. For the porphyrin series, a comparison of fully conjugated oligomers exhibiting the general structure (trans-bis(para-ethynyl(zinc(porphyrin)))bis(phosphine)platinum(II))(n) (i.e., the C(6) H(4) group is absent from the main chain) will be made. This contribution also includes a description of the properties of the mononuclear chromophore itself, properties that define those of the polymers. Potential applications with regard to electronic and optical devices will be highlighted. These soluble and stable materials feature both the processing advantages of polymers and the functionality provided by the presence of metal centers. These multifunctional organometallic polyyne polymers exhibit convenient structural variability as well as optical and electronic properties, which renders them important for use in different research domains as chemical sensors and sensor protectors, as converters for light/electricity signals, and as patternable precursors to magnetic metal alloy nanoparticles.

“…Both bond lengths and angles of the coordination sphere are comparable with those of similar structures retrieved in the Cambridge Structural Database [11] (CSD) v.5.25. The coordination plane and that containing the nitrophenyl moiety are almost coplanar (the angle is 3.8(2)°) at variance with similar structures, featuring the same trans-bis(ethynyl-p-nitrophenyl) ligand [12]. The ethynyl moiety is essentially linear being the angles Pt(1)-C(1)-C(2) and C(1)-C(2)-C(3), respectively, 176.7(7)°and 176.0(8)°.…”
