Oligomers of the low-band-gap PCDTBT polymer, based on either 3,6 or 2,7 carbazole units, were modified with vinyl ω-chain end functionalities. The vinyl-functionalized oligomers were used as comonomers in free radical polymerizations with quinoline-based monomers such as 6-vinylphenyl-(2-pyridinyl)-4-phenyl-quinoline (vinyl-QPy), and 6-vinylphenyl-(2-perfluorophenyl)-4-phenyl quinoline (vinyl-5FQ). The co-polymeric materials bearing the vinyl-QPy moiety were developed as potential compatibilizers in polymer electron donor⁻fullerene acceptor blends for non-covalent interactions with the fullerene part. The co-polymeric materials bearing the vinyl-5FQ moiety were developed for the covalent attachment of carbon nanostructures; specifically, PCBM. Both copolymers and hybrids, after thorough purification, were characterized in terms of their spectroscopic and optical properties as well as their ability to form nanophased separated films as such, or as additives at various percentages into PCDTBT: PCBM blends.
基于3,6或2,7咔唑单元的低带隙聚(咔唑并噻吩并苯并噻二唑)(PCDTBT)聚合物低聚物,用乙烯基ω链端官能团进行了改性。乙烯基官能化的低聚物被用作自由基聚合中的共聚单体,与喹啉基单体如6-乙烯基苯基-(2-吡啶基)-4-苯基喹啉(乙烯基-QPy)和6-乙烯基苯基-(2-全氟苯基)-4-苯基喹啉(乙烯基-5FQ)进行反应。带有乙烯基-QPy部分的共聚物材料被开发为聚合物电子给体-富勒烯受体共混物中的潜在增容剂,用于与富勒烯部分进行非共价相互作用。带有乙烯基-5FQ部分的共聚物材料被开发用于碳纳米结构的共价连接;具体来说,是与苯基-C61-丁酸甲酯(PCBM)连接。经过彻底纯化后,共聚物和杂化材料通过光谱和光学性质以及它们形成纳米相分离膜的能力进行了表征,这些膜可以单独形成,也可以以不同百分比作为添加剂加入到PCDTBT:PCBM共混物中。
