A novel electron-deficient building block, 5,5'-diazaisoindigo (5DNIID), was synthesized through a facile method in good yield. As a derivative of isoindigo, 5DNIID shows an ultra-low LUMO level of -3.92 eV after incorporation of two electron-deficient nitrogen atoms into the para-position of the amine groups in the isoindigo π skeleton. Modified polymerization conditions were applied to efficiently afford the donor-acceptor (D-A) conjugated polymer 5DNIID-2T, which exhibited a p-type charge transport property.
通过一种简便的方法以良好的产率合成了一种新型缺电子结构单元5,5'-二氮杂异靛蓝（5DNIID）。作为异靛蓝的衍生物，5DNIID在异靛蓝π骨架的胺基对位引入两个缺电子氮原子后，显示出-3.92 eV的超低最低未占分子轨道（LUMO）能级。采用改进的聚合条件有效地制备了供体-受体（D-A）共轭聚合物5DNIID-2T，其表现出p型电荷传输特性。
