摘要:
以共轭侧链含氯原子的苯并[1,2-b:4,5-b’]二呋喃(BDF)作为电子给体单元,以1,3-双(噻吩-2-基)-5,7-双(2-乙基己基)苯并[1,2-c:4,5-c’]二噻吩-4,8-二酮(BDD)为电子受体单元,设计合成了一种宽带隙共轭聚合物PBDF2Cl-BDD。该聚合物具有较宽的光学带隙(>1.82 eV)和较深的最高占据分子轨道能级。当聚合物给体与受体Y6搭配时实现了2.49%的能量转换效率,其开路电压为0.39 V,短路电流密度为16.50 mA·cm-2,填充因子为0.38。
Abstract:
A wide bandgap conjugated poly[(2,6-(4,8-bis(4-chloro-5-ethylhexyl)thiophen-2-yl)-benzo[1,2-b:4,5-b’]difuran))-alt-(5,5-(1’,3’-di-2-thienyl-5’,7’-bis(2-ethylhexyl)benzo[1’,2’-c:4’,5’-c’]dithiophene-4,8-dione (PBDF2Cl-BDD) was designed and synthesized using benzo[1,2-b:4,5-b’]difuran flanked with chlorinated thienyl groups and 1,3-bis(thiophen-2-yl)-5,7- bis(2-ethylhexyl)benzo[1,2-c:4,5-c’]dithiophene-4,8-dione as the electron donor unit and electron acceptor unit, respectively. The polymer PBDF2Cl-BDD has a wide bandgap(>1.82 eV)and a deep-lying highest occupied molecular orbit energy level. The power conversion efficiency reaches 2.49% based on the blend of PBDF2Cl-BDD and the non-fullerene acceptor Y6. The open circuit voltage and the short-circuit current density are 0.39 V and 16.50 mA·cm-2,respectively,and the fill factor is 0.38.
