Perfluorophenyl functionalities have been introduced as chain substituents onto regioregular poly(3-hexyl thiophene) (-P3HT), under various percentages. These functional groups were then converted to azides which were used to create polymeric hybrid materials with fullerene species, either C or C. The P3HT⁻fullerene hybrids thus formed were thereafter evaluated as potential compatibilizers of BHJ active layers comprising P3HT and fullerene based acceptors. Therefore, a systematic investigation of the optical and morphological properties of the purified polymer⁻fullerene hybrid materials was performed, via different complementary techniques. Additionally, P3HT:PCBM blends containing various percentages of the herein synthesized hybrid material comprising -P3HT and C were investigated via Transmission Electron Microscopy (TEM) in an effort to understand the effect of the hybrids as additives on the morphology and nanophase separation of this typically used active layer blend for OPVs.
全氟苯基官能团已在不同百分比下作为链取代基引入到区域规整的聚（3-己基噻吩）（-P3HT）上。然后将这些官能团转化为叠氮化物，用于与富勒烯物种（C或C）制备聚合物杂化材料。由此形成的P3HT⁻富勒烯杂化物随后被评估为包含P3HT和基于富勒烯的受体的BHJ活性层的潜在增容剂。因此，通过不同的互补技术对纯化的聚合物⁻富勒烯杂化材料的光学和形态学性质进行了系统研究。此外，通过透射电子显微镜（TEM）研究了含有不同百分比本文合成的包含-P3HT和C的杂化材料的P3HT:PCBM共混物，以了解杂化物作为添加剂对这种常用于OPV的活性层共混物的形态和纳米相分离的影响。
