Aggregation‐Induced Emission By combining advantages of triphenylethene (TriPE) and spiro‐acridine‐fluorene (SAF) groups, a series of novel aggregation‐induced emission (AIE) compounds named SAF‐2‐TriPE, SAF‐3‐TriPE, and SAF‐4‐TriPE were designed and synthesized by using facile reaction procedures. While SAF‐2‐TriPE and SAF‐3‐TriPE showed normal AIE phenomena, SAF‐4‐TriPE held interesting optical properties. The SAF‐4‐TriPE emitted strong fluorescence in both pure THF solution and in the aggregated state without a significant change in Φ F . In addition, the external quantum efficiency (EQE) of the non‐doped device based on SAF‐2‐TriPE was as high as 4.22 %. For more details, see the Full Paper by Z.‐Q. Jiang, L.‐S.
