Ladder‐type Heteroarenes: Up to 15 Rings with Five Imide Groups. Issue 33 (28th June 2017) - Wang, Yingfeng
Abstract: A series of novel imide‐functionalized ladder‐type heteroarenes with well‐defined structure and controllable conjugation lengths were synthesized and characterized. The synthetic route shows remarkable efficacy for constructing the electron‐deficient ladder backbones. π‐Conjugation extension leads to narrowed band gaps with enhanced electron affinities. The ladder arenes are incorporated into organic thin‐film transistors, and show encouraging electron mobilities of 0.013–0.045 cm 2 V −1 s −1 . The heteroarenes reported here provide a remarkable platform for fundamental physicochemical studies and materials innovation in organic electronics. Abstract : Climbing the ladder : A series of novel ladder‐type heteroarenes with well‐defined structures and precisely controllable conjugation lengths were synthesized with remarkable efficacy and characterized. Compared to most ladder‐type arenes, these imide‐functionalized building blocks are highly electron‐deficient, and thus provide a remarkable platform for materials innovation in organic electronics.
