中文摘要：

氟代喹喔啉（FTQ）是一种氟代结构的受体单元,可以用于构筑D-A型聚合物,并应用于聚合物太阳电池的给体材料。文中探索了一种新的起始原料合成氟代喹喔啉单体,并分别和齐聚四噻吩单体（4T）、单噻吩单体（1T）共聚,得到了2个新型聚合物PFTQ-4T和PFTQ-1T,表征测试了它们的相对分子质量、热性能、紫外吸收、能级结构以及光伏性能。2个聚合物的能量转化效率分别为0.73%和1.28%,较低效率主要是2个聚合物较低的LUMO 能级所导致。

英文摘要：

Fluorinated quinoxaline （FTQ） is an electron-accepting unit to construct D-A conjugated polymers for polymer solar cells（PSC）. In this work, a new synthetic route from a new starting material was proposed for the FTQ monomer, from which FTQ-based new copolymers FTQ-4T and FTQ-1T with quaterthiophene （4T） and single thiophene （1T） as the D-unit, respectively, were successfully synthesized. The molecular weights, thermal properties, UV-vis absorptions, energy levels, and photovoltaic performances of the two copolymers were evaluated. Polymer solar cells show power conversion efficiencies of 0.73% and 1.28% for PFTQ-4T and PFTQ-1T, respectively. Too low LUMO levels of the two copolymers should be responsible for their not high power conversion efficiencies.
