Abstract

The nanorheological approach for characterization of electroluminescent polymer thin films was presented. The photoluminescence quantum efficiency of poly(p-phenylenevinylene) (PPV) was directly correlated to the glass transition property. As a function of the conversion temperature of the soluble PPV precursor, conformational changes and chain packing were discussed.
