Aggregation-induced emission luminogens (AIEgens) have been widely used in organic light-emitting diodes (OLEDs), but few works have reported on utilizing AIEgens as hosts in doped OLEDs. In this work, a new AIEgen of TPP-mCP was designed and synthesized by integrating a typical AIE moiety of tetraphenylpyrazine (TPP) with a conventional host of 1,3-di(9H-carbazol-9-yl)benzene (mCP). TPP-mCP exhibits better thermal and conformational stability and carrier capacity, and higher emission efficiency in the film state than those of mCP. More importantly, the OLEDs fabricated with TPP-mCP as the host show much higher electroluminescent performance than those with mCP. Thus, this work not only generates a new AIE-active host of TPP-mCP with high device performance, but also provides a strategy to construct more effective hosts by decorating conventional ones with AIE units, which will potentially promote the development of OLEDs.

四苯并吡嗪修饰的1,3-二(9 H-咔唑-9-基)苯(mCP):一种新型的AIE活性主体,在有机发光二极管中具有增强的性能†
聚集诱导发射发光剂(AIEgens)已被广泛用于有机发光二极管(OLED)中,但是很少有人报道将AIEgens用作掺杂OLED中的主体。在这项工作中,通过将典型的四苯基吡嗪(TPP)的AIE部分与常规的1,3-二(9 H-咔唑-9-基)苯(mCP)主体整合,设计并合成了一种新的TPP-mCP AIEgen。TPP-MCP表现出更好的比的薄膜状态的热和构象稳定性和载体容量,及发光效率更高的mCP。更重要的是,以TPP-mCP为基质制造的OLED的电致发光性能比mCP更高。。因此,这项工作不仅产生了具有高设备性能的新型AIE主动TPP-mCP主机,而且还提供了一种通过用AIE单元装饰传统主机来构建更有效主机的策略,这将潜在地促进OLED的发展。
