  Polymer Nanocomposites Containing Superstructures of Self-Organized Platinum Colloids

  摘要：

  Colloidal platinum (diameter 1-2 nm) in styrene was prepared in situ by reduction of a platinum(II) compound followed by partial evaporation of styrene, The resulting dispersions were purified from the reaction side-products, and ammonium O,O ' -dialk-yldithiophosphates of different chain length or octadecanethiol was added. Polymerization was started with a radical initiator. Several parameters were varied and, particularly in the presence of long-chain dialkyldithiophosphates, self-assembled superstructures of metal colloids appeared at certain conditions in the resulting poly(styrene)-platinum nanocomposites. Unusual hollow shell structures of typical diameters of 50-300 nm were found, which phenomenologically resembled bilayer vesicles in aqueous solutions, although the formation mechanism of the bilayers and the superstructures in the nanocomposites is considered to differ. It is supposed that the formation of the superstructures in the nanocomposites is induced by crystallization of alkyl chains adsorbed at the platinum surface below monolayer coverage.

• Two Alternative, Convenient Routes to Bis(diphenylacetylene)platinum(0)
  作者：Christian Huber、Akshay Kokil、Walter R. Caseri、Christoph Weder

  DOI：10.1021/om020230h

  日期：2002.9.1

  Two new synthetic routes are presented that allow the convenient preparation and isolation of bis(diphenylacetylene)platinum(0) under ambient conditions. The first procedure is based on a ligand exchange reaction between Ph−C⋮C−Ph and tris(styrene)platinum(0). The second framework relies on the reduction of cis-[PtCl2(PhCHCH2)2] with triphenylsilane in the presence of diphenylacetylene.

  提出了两种新的合成路线，这些路线允许在环境条件下方便地制备和分离双（二苯基乙炔）铂（0）。第一个步骤基于Ph-C⋮C-Ph与三（苯乙烯）铂（0）之间的配体交换反应。第二个框架依赖于在二苯基乙炔存在下用三苯基硅烷还原顺式-[PtCl 2（PhCH CH 2）2 ]。
• Synthesis and characterization of liquid platinum compounds

  Liquid platinum complexes were obtained with a ligand with alkyl chains that attach to the coordination plane perpendicularly and herewith render a close packing of the molecules difficult for certain chain lengths. Bis(O, O'-dialkyldithiophosphato)platinum(II) complexes, Pt(C(x)dtp)(2) where the alkyl chains are methyl (x = 1), ethyl (x = 2), propyl (x = 3), butyl (x = 4), pentyl (x = 5), hexyl (x = 6), heptyl (x = 7), dodecyl (x = 12), and octadecyl (x = 18), were investigated. The platinum compounds were synthesized via two routes: reaction of tetrachloroplatinate(IT) with ammonium-O,O'-dialkyldithiophosphates or oxidative addition of (O,O'-dialkylthiophosphoryl)disulfides to tris(styrene)platinum(0). The melting temperatures as a function of the alkyl chain length show a minimum for the complex with pentyl groups. The complexes with pentyl and hexyl groups are liquid at room temperature, and the complexes with butyl and heptyl groups melt only slightly above room temperature. Depending on the complex, the low melting temperatures are induced by an unfavorable packing of the molecules in the solid state, reflected in a low melting enthalpy, or melting entropy. The molecular weights of the liquid complexes are between 700 and 800 and, therefore, extraordinarily high for liquid metal compounds. Depending on the alkyl groups, the complexes decompose at 172-241 degrees C. Crystals of bis(O,O'-diethyldithiophosphato)platinum(II), Pt(C(2)dtp)(2), are monoclinic, space group P2(1)/n, a = 8.90, b = 8.70, c = 12.45 Angstrom, alpha = gamma = 90 degrees, beta = 100.89 degrees, and Z = 4.

• High Charge Carrier Mobility in Conjugated Organometallic Polymer Networks

  The improvement of charge transport in conjugated polymers is a focal point of current research. It is shown here that the carrier mobility can be substantially increased through the introduction of conjugated cross-links between the conjugated chains. Novel organometallic polymer networks based on a poly(p-phenylene ethynylene) (PPE) derivative and Pt0 were synthesized by ligand-exchange reactions between the linear PPE and a low-molecular Pt complex. Time-of-flight measurements revealed ambipolar charge carrier mobilities of up to 1.6 x 10-2 cm2 V-1 s-1 for these materials, which are an order of magnitude higher than those of the neat polymer and represent the highest mobilities yet observed in disordered conjugated polymers.

  Kinetic measurements and 1H, 2H and 195Pt NMR studies have been carried out on the platinum catalysed hydrosilylation of styrene with triethylsilane. With trans-PtCl2(PhCHCH2)2 as catalyst precursor there is a short period during which reduction and product development take place, but with Pt(PhCHCH2)3 the product development is linear and a plot of the yield of product against time passes through the
