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)的聚对苯撑乙炔,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。
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 these polymers can be easily and significantly influence by the nature of the alkoxy substituents and their molecular weights, UV-Vis, PL of polymers were measured respectively.
