Herein, two red luminogens with aggregation-induced emission (AIE) characteristics based on simple D–A structures with high performance in the film state are explored. Efficient non-doped solution-processed organic light emitting diodes (OLEDs) are fabricated and emit bright red electroluminescence at 652 nm and 711 nm, respectively. Most importantly, they exhibit CIE coordinates of (0.63, 0.36) and (0.64, 0.35), respectively, which are close to that of primary red color (0.63, 0.34) according to the digital television standard.
