侧链对聚对苯撑乙炔溶解性和光谱性能的影响

Influence of Side Alkoxy on the Solubility and Spectrum of Poly(p-Phenylenethynylene)s

摘要: 利用钯催化反应合成了一类侧链含不同烷氧取代基(甲氧基，辛烷氧基，十二烷氧基)的聚时苯撑乙炔，讨论了侧链烷氧取代基对聚对苯撑乙炔的分子量和溶解性的影响，比较了聚合物的紫外吸收光谱和荧光光谱特征。

Abstract: A series of poly(p-phenyleneethynylene)s were prepared by the palladium-catalyzed cross-coupling polycondensation. By introducing different alkoxy(such as: -OCH_3, -OC_8H_(17), -OC_(12)H_(23) ) on the aromatic rings, it is found that the solubility of the
