摘要：

Conjugated polymers and oligomers of thiophene have been employed in a number of electronic devices due to the change in their conductivity by several orders of magnitude when oxidized to their cationic states. The radical cations of oligothiophenes (nT), with number of rings n = 1-6, have been produced by pulse radiolysis for the first time and their spectra have been characterized. Electronic structure and transition energies are briefly discussed in the light of semiempirical theoretical calculations. (C) 1999 Elsevier Science Ltd. All rights reserved.
