A new highly efficient near‐infrared organic light‐emitting material is reported by Zuo‐Quan Jiang, Liang‐Sheng Liao, and co‐workers in article number 1700986 . The donor‐acceptor intramolecular interaction accounts for the near‐infrared emission whereas the applied strong electron‐withdrawing unit acenaphtho[1,2‐b]pyrazine‐8,9‐dicarbonitrile is proposed for the first time. Under the mechanism of thermally activated delayed fluorescence, it exhibits over 10% external quantum efficiency with the peak of 693 nm.
