摘要

Fully soluble poly[2-methoxy-5-(2'-ethylhexyl)-oxy)-p-phenylenevinylene] (MEH-PPV) was synthesized by theaddition of molecular weight modifiers (chain stopper

free radical scavengers) to a polymerization system containingmonomer

catalyst and a solvent. These PPV products synthesized in this work were characterized by IR

NMR

UV-visiblespectroscopy and GPC. Results show that the Mw of polyphenylvinylene (PPV) can be controlled by the addition of chainstopper (benzyl bromide) and radical inhibitor (2

6-di-tert-butyl-4-methyl phenol).The polymerization mechanism in the presence of these additives was also discussed.A dual mechanism involving carbene for PPV polymerization was proposed.
