【 摘 要 】

A studyis presented of the formation and optical properties of polymeric heterostructuresfrom poly(p-phenylene vinylene) (PPV) and poly(o-methoxyaniline)(POMA) produced via the self-assembly technique. POMA layers were obtained ina non self-limiting process from its emeraldine salt, semiconducting form inHCl solution. Thermal conversion of PPV was performed at low temperatures withthe substitution of the counter-ion Cl in the PPV precursor by a long sulfonicchain, the dodecylbenzenesulfonate (DBS) ion. The optical properties of PPVfilms converted in this way are not affected by POMA, which can be used as transparentelectrode of PPV luminescent devices.
