    Notes: From Wittig-reactions of thieno[2,3-b]thiophene-2,5-dicarboxaldehyde (1) and thieno-[3,2-b]thiophene-2,5-carboxaldehyde (4) with “mono-and bis Wittig-salts” of the benzene and thiophene series two series of isomeric poly(thienothiophene-2,5-diylvinylenearylenevinylene)s 3a - c and 5a - c, and some model compounds 7a - c and 8a - c were obtained. Wittig-reacaldehyde (11) with “mono-and bis-Wittig-salts” gave two series more of model compounds 10a - c, 12a - c, 13a, c, 14a, c. The structure of all compounds were confirmed by elemental analyses, IR, and electronic spectra, and those of the model compounds additionally by mass spectra, and in case of sufficient solubility by 1 H NMR spectra. The electrical conductivities of all compounds and the thermooxidative degradation of the polymers were investigated.
