Abstract
A homologous series of ring-substituted dialkoxy-PPV precursors have b een synthesized and characterized. By increasing the number of methyle ne units in the side groups up to six, a linear decrease of the glass transition temperature is found, with a span of ca. 100 degrees C, goi ng from 92 degrees C down to -11 degrees C. T.m.a. experiments reveal high stretchability of thin films at temperatures just above T-g witho ut elimination. The thermal conversion of the precursor polymer into t he conjugated materials was studied and with controllable amounts of c atalytic 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.
