Abstract：
Two blue-emitting materials, 4-(12-([1,1\':3\',1″-terphenyl]-5\'-yl)chrysen-6-yl)-N,N-diphenylaniline (TPA-C-TP) and 6-([1,1\':3\',1″-terphenyl]-5\'-yl)-12-(4-(1,2,2-triphenylvinyl)phenyl)chrysene (TPE-C-TP), were prepared with the composition of a chrysene core moiety and terphenyl (TP), triphenyl amine (TPA), and tetraphenylethylene (TPE) moieties as side groups. The maximum photoluminescence (PL) emission wavelengths of TPA-C-TP and TPE-C-TP were 435 and 369 nm in the solution state and 444 and 471 nm in the film state. TPA-C-TP effectively prevented intermolecular packing through the introduction of TPA, a bulky aromatic amine group, and it showed an excellent photoluminescence quantum yield (PLQY) of 86% in the film state. TPE-C-TP exhibited aggregation-induced emission; the PLQY increased dramatically from 0.1% to 78% from the solution state to the film state. The two synthesized materials had excellent thermal stability, with a high decomposition temperature exceeding 460 °C. The two compounds were used as emitting layers in a non-doped device. The TPA-C-TP device achieved excellent electroluminescence (EL) performance, with Commission Internationale de L\'Eclairage co-ordinates of (0.15, 0.07) and an external quantum efficiency of 4.13%, corresponding to an EL peak wavelength of 439 nm.
摘要：
两种发蓝光的材料，4-(12-([1,1\'：3\'，1″-三联苯]-5′-基)chrysen-6-基)-N,N-二苯基苯胺(TPA-C-TP)和6-([1,1\':3\',1″-三联苯]-5′-基)-12-(4-(1,2,2-三苯基乙烯基)苯基(TPE-C-TP),用菊心部分和三联苯(TP)的组成制备，三苯基胺（TPA），和四苯基乙烯(TPE)部分作为侧基。TPA-C-TP和TPE-C-TP的最大光致发光(PL)发射波长在溶液状态下为435和369nm,在膜状态下为444和471nm。TPA-C-TP通过引入TPA有效防止了分子间的堆积,庞大的芳香胺基，在薄膜状态下表现出86％的优异的光致发光量子产率（PLQY）。TPE-C-TP表现出聚集诱导的发射；从溶液状态到膜状态，PLQY从0.1％急剧增加到78％。两种合成材料均具有优异的热稳定性,具有超过460°C的高分解温度。这两种化合物用作非掺杂器件中的发光层。TPA-C-TP器件实现了优异的电致发光(EL)性能,国际委员会的计算坐标为(0.15，0.07)，外部量子效率为4.13%，对应于439nm的EL峰值波长。
