摘要：

Anodic coupling of bisdithienylethylene is reported. The resulting material, which has been characterized by cyclic voltammetry, UV-vis. Fourier transform infrared (FTIR) and matrix-assisted laser desorption ionization (MALDI) mass spectroscopies and in situ conductivity, results to be mainly constituted by the dimer coupled through the a-thiophene positions. In situ (solid state) polymerization increases the degree of polymerization from 2 to ca. 5. The conjugation (lambda(max) = 490 nm) and conductivity (5 S cm(-1)) of the polymer are slightly lower than those of poly(dithienylethylene) (505 nm and 30 S cm(-1)). (C) 1999 Elsevier Science S.A.
