摘要:
基于高性能半导体聚合物给体聚[(2,6-(4,8-双(5-(2-乙基己基)-噻吩-2-基)-苯并[1,2-b:4,5-b’]二噻吩))-alt-(5,5-(1’,3’-二-2-噻吩基)-5’,7’-双(2-乙基己基)苯并[1’,2’-c:4’,5’-c’]二噻吩-4,8-二酮)](PBDB-T),通过Stile偶联聚合反应,首次合成了一种含非共轭单元的新型聚合物给体材料聚[(2,6-(4,8-双(5-(2-乙基己基)-噻吩-2-基)-苯并[1,2-b:4,5-b’]二噻吩))-(5,5-(1’,3’-二-2-噻吩基)-5’,7’-双(2-乙基己基)苯并[1’,2’-c:4’,5’-c’]二噻吩-4,8-二酮)-1,3-双(2-噻吩基)丙烷](PDBS-5),并将其应用于有机太阳能电池。紫外-可见光谱表明:相比于PBDB-T,非共轭单元的引入降低了PDBS-5吸收光谱中堆积峰的吸收强度,表明分子间π-π堆积减弱;循环伏安测试表明非共轭单元的引入降低了聚合物的能级。基于PDBS-5:IT-4F共混膜制备出能量转换效率达到7.42%的有机太阳能电池。研究结果表明含非共轭单元的聚合物PDBS-5是有潜力的有机太阳能电池给体材料。
Abstract:
A new type of polymer poly[(2,6-(4,8-bis(5-(2-ethylhexyl)thiophen- 2-yl)-benzo[1,2-b:4,5-b’]dithiophene))-(5,5-(1’,3’-di-2-thienyl)-5’,7’-bis(2-ethylhexyl)benzo[1’,2’-c:4’,5’-c’]dithiophene-4,8-dione)-1,3-bis(2-thienyl)propane](PDBS-5) containing non-conjugation spacers was synthesized via Stile coupling polymerization based on the high-performance semiconductor polymer donor poly[(2,6-(4,8-bis(5-(2-ethylhexyl)thiophen- 2-yl)-benzo[1,2-b:4,5-b’]dithiophene))-alt-(5,5-(1’,3’-di-2-thienyl)-5’,7’-bis(2-ethylhexyl)benzo[1’,2’-c:4’,5’-c’]dithiophene-4,8-dione)](PBDB-T) for the first time, and used as the donor material in organic solar cells. The reduced absorption intensity of the stacking peak in the PDBS-5 absorption spectra indicates that the introduction of non-conjugation spacers weakens the intermolecular π-π stacking compared with that of PBDB-T. The introduction of non-conjugation spacers also decreases the energy levels of the PDBS-5 which is verified via cyclic voltammetry experiment. The organic solar cells based on PDBS-5:IT-4F blend deliver a power conversion efficiency of 7.42%. These results indicate that the polymer PDBS-5 containing non-conjugation spacers is a promising donor material for organic solar cells.
