Ladder-type Heteroarenes: Up to 15 Rings with Five Imide Groups

Angew Chem Int Ed Engl. 2017 Aug 7;56(33):9924-9929. doi: 10.1002/anie.201702225. Epub 2017 Jun 28.

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 cm2 V-1 s-1 . The heteroarenes reported here provide a remarkable platform for fundamental physicochemical studies and materials innovation in organic electronics.

Keywords: conjugation; heteroarenes; ladder polymers; semiconductors; structure-activity relationships.
