摘要：

Poly(1,4-phenylenevinylene) and poly(1,4-phenyleneethynylene) were prepared from trans-1,2-dibromoethylene and 1,4-bis(2-bromoethynyl)benzene respectively with aryldiboronic acids by a Suzuki cross-coupling reaction. The polymers were synthesized in a two-phase system at room temperature using silver oxide and a Pd catalyst. 3% of biaryl formation is observed as a defect structure in the PPV polymers resulting from coupling of arylboronic acid. Soluble polymers were obtained when the aryldiboronic acid is substituted with long-chain alkoxy groups.
