| Popis: |
A series of 2,5-bis(2-thienyl)pyrroles has been synthesized in which the α-thiophene protons and/or the β-pyrrole protons have been replaced by Me or Br substituents. A systematic electrochemical investigation of these compounds has yielded rate constants of 36 000 M -1 s -1 for linear couplings of the electrochemically generated cation radicals and 14 000-17 000 M -1 s -1 for branched coupling reactions of the cation radicals. These results constitute the first kinetic evidence foir appreciable branched coupling of the electrochemical radical cations of an oligomer precursor of a conducting polymer |
