  Practical Synthesis of Vinyl-Substitutedp-Phenylenevinylene Oligomers and Their Triethoxysilyl Derivatives

  摘要：

  Luminescent semiconducting organic compounds are widely used as active layers in electro-optical devices. Apart from conjugated polymers, monodisperse oligomers also represent attractive materials. The synthesis of stilbenoid oligomers with polymerizable end groups is presented. Oligo(phenylenevinylene)s with terminal vinyl groups 17-19 are prepared in good yields by Horner-Emmons olefinations or by the fleck reaction of the iodo-substituted oligomers 15, 16 with cornpressed ethene. Triethoxysilyl groups can be linked via rigid 1,2-vinylene units to the chromophores 26-30, either in the direct reaction of 14, 24 with silanes 21, 22 or by cross-metathesis of 17-19 with the vinyl silanes 21, 22 using Grubbs catalyst.
