| Résumé : | A homologous series of ring-substituted dialkoxy-PPV precursors have been synthesized and characterized. By increasing the number of methylene units in the side groups up to six, a linear decrease of the glass transition temperature is found, with a span of ca. 100°C going from 92°C down to -11°C. T.m.a. experiments reveal high stretchability of thin films at temperatures just above Tg without elimination. The thermal conversion of the precursor polymer into the conjugated materials was studied and with controllable amounts of catalytic acid in the thin films, a well-defined processing window can be established in order to prepare stretched, conjugated thin films of dialkoxy-PPV material.
