Definition of polyacetylene in English:



mass nounChemistry
  • A black electrically conducting solid which is a hydrocarbon polymer containing chains of carbon atoms joined by alternate double and single bonds.

    • ‘One such early material was AsF 5 doped cis polyacetylene - this was not a pleasant dopant to use, but it increased the polymer's conductivity by a factor of as much as 10 11.’
    • ‘In addition, certain polyacetylene constituents of Echinacea have been found to be bacteriostatic against E. coli and Pseudomonas aeruginosa.’
    • ‘Both luck and insight played roles in the discovery of the first conducting polymer, a form of the material called polyacetylene.’
    • ‘First, researchers found that when the polymer polyacetylene acquires an extra electron, the particle seems to split into two quasi-particles, or excitations of the molecule as a whole.’
