摘要

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
