Interchain luminescence in poly(acetoxy-p-phenylene vinylene)

The synthesis of a new substituted poly(phenylene vinylene) (PPV) derivative poly(acetoxy-p-phenylene vinylene) is reported. A new pathway, combining chemical and electrochemical steps was employed, resulting in a highly regular, polar, monosubstituted PPV. The participation of excimers and/of aggregates as emitting units in PPV and some of its derivatives has been demonstrated previously in various papers. This contribution provides evidence from fluorescence studies of the participation of those associated forms in the emission of this novel structure. A pattern of progressive fluorescent aggregate formation was observed, a result not reported to date.
