We synthesized n-type polymers poly{[N,N'-bis(2-octyldodecyl)-naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]-alt-5,5'-(2,2'-bithiophene)} [P(NDI2OD-T2)] and poly{[N,N'-bis(3-(4-cardanol)propyl)-naphthalene-1,4,5,8-tetracarboxylic diimide]-alt-[5,5'-bis(2-thienyl)-2,2'-bithiophene]} [P(NDICL-T2)] with cardanol-based side chains via Stille coupling to enhance electron mobility. Replacing the 2-octyldodecyl side chain with cardanol in P(NDICL-T2) improved electron mobility due to increased chain flexibility and ordered packing. Lower glass transition temperature (), red-shifted UV-vis absorption, results from crystalline structure analysis, indicating tighter lamellar spacing and enhanced molecular ordering, and smoother surface morphology confirmed the enhanced intermolecular interactions and uniform film formation.
我们通过Stille偶联反应合成了带有基于腰果酚侧链的n型聚合物聚{[N,N'-双(2-辛基十二烷基)-萘-1,4,5,8-双(二甲酰亚胺)-2,6-二基]-alt-5,5'-(2,2'-联噻吩)} [P(NDI2OD-T2)]和聚{[N,N'-双(3-(4-腰果酚)丙基)-萘-1,4,5,8-四羧酸二亚胺]-alt-[5,5'-双(2-噻吩基)-2,2'-联噻吩]} [P(NDICL-T2)]，以提高电子迁移率。在P(NDICL-T2)中用腰果酚取代2-辛基十二烷基侧链，由于链柔性增加和有序堆积，提高了电子迁移率。较低的玻璃化转变温度、紫外-可见吸收红移，晶体结构分析结果表明层间距更紧密、分子有序性增强，表面形态更光滑，证实了分子间相互作用增强和薄膜形成均匀。
