Chlorine precursor route to poly(2-phenoxy p-phenylene vinylene): synthesis and characterization

A new PPV derivative, poly(2-phenoxy p-phenylene vinylene)(PO-PPV), has been synthesized via the chlorine precursor route (CPR). PO-PPV and its chlorine precursor polymer were fully characterized by thermal (TGA and DSC), mechanical and spectroscopic (UV-vis, PL and IR) methods. The results indicate that the precursor polmer and the yellow-green light-emitting PO-PPV have excellent stability and mechanical properties. The easily processible precursor is stable at room temperature and therefore has a better shelf-life than PPV synthesized via the sulfonium precursor route. Thermal conversion provides high quality films, relatively free of oxidative defects.
