Composites of PPV in PVA, PVK and other polymeric matrixes were prepared by an in-situ polymerization of 1,4 phenylene dimethylene-bis-(tetramethylene sulfonium chloride) or □□□′-dibromo-p-xylene. The monomer was converted directly to PPV in the polymeric matrix. This polymerization technique was successfully carried out by the use of a base, at room temperature, without requiring removal of oligomers and was completed in several minutes. EL and PL of the composites were measured and compared with PPV. A blue shift was found in the PL spectrum of the PPV-PVA composite compared to PPV. Other composites showed similar PL to that of PPV.
