Description:
AbstractStarting from 2,3,6‐trimethylthiazolo[4,5‐f] benzothiazolium perchlorate (2b) some poly(5‐methylthiazolo[4,5‐f] benzothiazolium‐2,6‐diylvinylenarylenevinylene)s (11a–c) and some corresponding model compounds (10a–c) were prepared via Knoevenagel condensation with mono‐and dialdehydes (4 and 6) of the benzene and thiophene series. Additional series of model compounds (5a–c, 7a–c, 8a–f, and 9a–f) were obtained from 2,3,6‐trimethylthiazolo[4,5‐f]benzothiazolium iodide (2a) or 2,3‐dimethylbenzothiazolium iodide (3a), respectively, or from the perchlorates (2b and 3b) submitted to the same reaction with mono‐and dialdehydes. The structure of these model compounds and polymers was confirmed by elemental analyses, IR and electronic spectra. The model compounds are also characterized by their mass spectra, and in the case of sufficient solubility by 1H NMR spectroscopy too. The electrical conductivities of all compounds and polymers and the thermooxidative degradation of the polymers were investigated.
