摘要：

The formation of high molecular weight products by the synthesis of poly(2,5-trienylene ethylene) from alkyne metathesis was discussed. Coupling reactions of diethynylated aromatics with dihalogenated arenes was performed in the synthesis process using Shrock tungsten carbyne complex as the catalyst. The PAE (poly(aryleneethnylene)s was synthesized by the polymerization reaction for the removal of alkyne byproduct. It was found that the low boiling point of 2, butyne helped the removal of the byproduct and a higher molecular weight polymer.
