Abstract
The conversion of the precursor into poly(p-phenylene vinylene) PPV fi lms has been studied by X ray photoelectron spectroscopy (XPS) and ele ctron spin resonance (ESR) technique in the temperature range from 25 to 300 degrees C. XPS results revealed that the PPV films may contain impurities on their surface depending on the nature of the precursor u sed while ESR analysis showed a progressive disappearance of the radic als formed on the sulfur sites upon heating. These complementary studi es allowed us to determine the optimum rate of the conversion process.
