Abstract

Abstract: 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 polymer5DNIID‐2T, which exhibited a p‐type charge transport property. Abstract : A novel electron‐deficient building block, 5, 5′‐diazaisoindigo (5DNIID ), was synthesized through a facile method, which showed an ultra‐low LUMO level of −3.92 eV owing to the introduction of two electron‐deficient nitrogen atoms into the para ‐position of the amine groups in the isoindigo π skeleton. A donor–acceptor conjugated polymer5DNIID‐2T, which exhibited typical p‐type charge transport behavior, was constructed.
