  Synthesis and spectroscopic study of silacyclyne-substituted phenyleneethynylenes

  摘要：

  A series of 1,1-dimethyl-4,5:8,9-dibenzo-1-silacycloundeca-4,8-diene-2,6,10-triyne (DST)-substituted phenyleneethynylenes were successfully synthesized by reaction of Me2SiCl2 with dimagnesium dianions which had been prepared from 2,2'-diethynyl(diphenylethyne) derivatives by treatment with 2 equiv of MeMgBr. All the products were white-to-pale yellow powder stable enough to handle in the air, and their photoluminescence spectra were recorded both in solution and in solid state. (C) 2009 Elsevier Ltd.

  DOI：10.1021/om9507437

  日期：1996.5.28

  Efficient syntheses and characterization of-a platinum metallacyclyne containing one cyclic enyne pocket (3), the first dinuclear platinum metallacyclyne containing two cyclic enyne pockets (4), and 2,2',6,6'-tetraethynyltolan (2) are reported. Syntheses of 3 and 4 employ bidentate phosphines or cis-platinum starting materials and high dilution techniques to effect high yields.

  DOI：10.1002/cjoc.201190078

  日期：2011.2

  Syntheses and optical properties of cyclic arylethynylsilanes containing one or two trialkyne pockets were described. Optical properties such as UV‐vis spectra, photoluminescence and quantum yield based on these conjugated structural features were compared with each other. The photoactivated insecticidal activities against the 4th‐instar larvae of Aedes albopictus (Skuse) were evaluated.
