新型单体的设计和合成可能为高性能半导体聚合物创造新的机遇。本研究基于合理设计对异靛蓝相关构件进行了合成改性。以 5,5'-二乙烯基-2,2'-联噻吩作为共轭桥的扩展异靛蓝单元 (IBTI) 已成功整合到供体-受体共轭聚合物 PBDT-IBTI 中。这种新型聚合物在可见光区域表现出广泛的吸收和大的消光系数。这种新型聚合物的光学带隙、HOMO和LUMO能级分别为1.71 eV、-5.24 eV和-3.72 eV。基于PBDT-IBTI和(6,6)-苯基-C61丁酸甲酯(PC61BM)共混物的聚合物太阳能电池的PCE达到6.41%。这项工作表明 IBTI 是有机光伏 (OPV) 聚合物的一种有前途的构建模块。这些发现还揭示了羟吲哚作为异靛蓝类共轭单体的基本构建元件的多功能性。
Design and synthesis of novel monomers may create new opportunities for high performance semiconducting polymers. The synthetic modification of an isoindigo related building block based on rational design has been carried out in this study. An expanded isoindigo unit (IBTI) with 5,5′-divinyl-2,2′-bithiophene as a conjugated bridge has been successfully incorporated into a donor–acceptor conjugated polymer, PBDT–IBTI. The new polymer showed broad absorption and a large extinction coefficient in the visible region. The optical bandgap, HOMO and LUMO levels of this new polymer are 1.71 eV, −5.24 eV and −3.72 eV, respectively. The polymer solar cells based on PBDT–IBTI and (6,6)-phenyl-C61 butyric acid methyl ester (PC61BM) blends achieved a PCE of 6.41%. This work has demonstrated that IBTI is a promising building block for organic photovoltaic (OPV) polymers. These findings have also revealed the versatility of oxindole as the basic building element for isoindigo-like conjugated monomers.
