AB  - High-efficiency organic blue light-emitting materials are the key components to construct high-performance organic light-emitting diode (OLED) devices. In this research, a novel asymmetric pyrene-based blue emitter (TPE-o2Ph) with aggregation-induced emission (AIE) characteristics was synthesized. The pyrene-based AIE luminogen exhibits blue emission with the maximum emission peak (λem) at 460 nm and high fluorescence quantum yield of 0.90 in solid state. In addition, the compound TPE-o2Ph was utilized as the light-emitting layer for non-doped/doped blue OLED devices with excellent electroluminescence (EL) performance. Moreover, the non-doped OLED exhibits excellent EL performance, with a maximum luminescence (Lmax) and the maximum external quantum efficiency (EQE) of 12560 cd·m−2 and 2.34%.
