Several tetraphenylethene and triphenylamine decorated donor-acceptor (D-A) benzoselenadiazole derivatives with aggregation-induced emission (AIE) features were synthesized and characterized. The photophysical, thermal, electrochemical and electroluminescent (EL) properties, as well as the AIE property of the resulting luminogens are discussed. All the luminogens are soluble in common organic solvents and show high thermal stability with a T_d of 399–460 °C. The absolute photoluminescence quantum yield in the solid state ranged from 14.2% to 36.5%. The D–A structures of TPE-Se-TPE, TPA-Se-TPE and TPA-Se-TPA enable them to have aggregation-caused quenching (ACQ) plus aggregation-induced emission enhancement (AIEE) effects dominated by the twisted intramolecular charge-transfer (TICT) and restriction of intramolecular rotations (RIR), respectively. The best device performances were obtained from TPA-Se-TPE with a maximal luminous efficiency of 2.91 cd/A and the maximal brightness is 5855 cd/m². This is the first report of benzoselenadiazole-based fluorophore with an AIE feature for organic electronics application.

合成并表征了几种四苯乙烯和三苯胺修饰的具有聚集诱导发射（AIE）特征的供体-受体（DA）苯并硒二唑衍生物。讨论了所得光致发光剂的光物理，热，电化学和电致发光（EL）特性以及AIE特性。所有的发光剂都可溶于常见的有机溶剂，并在T _d时显示出高的热稳定性。399–460°C。固态的绝对光致发光量子产率为14.2％至36.5％。TPE-Se-TPE，TPA-Se-TPE和TPA-Se-TPA的D–A结构使它们具有聚集引起的猝灭（ACQ）以及聚集诱导的发射增强（AIEE）效应，该效应主要由扭曲的分子内电荷控制转移（TICT）和分子内旋转限制（RIR）。从TPA-Se-TPE获得最佳的器件性能，其最大发光效率为2.91 cd / A，最大亮度为5855 cd / m ²。这是基于苯并硒二二唑的具有AIE功能的荧光团在有机电子应用中的首次报道。
