Abstract A series of new asymmetric anthracene derivatives have been successfully synthesized for use in the light emitting layer of solution processed blue fluorescent organic light emitting diodes (OLEDs), which could be used both as host and dopant. Especially, new synthetic blue fluorescent materials with anthracene moieties without any alkyl chains showed high solubility in common organic solvents probably due to their severely twisted internal structures. They also show moderately high thermal stability due to their rigid internal core units. With those novel soluble blue fluorescent materials, we created moderately efficient solution-processed fluorescent OLEDs. And a new anthracene derivative [9-(9,10-di(naphthalen-2-yl)anthracen-2-yl)-9H-carbazole (DN-2-CzA)] as a host material exhibited moderately high efficiency and external quantum efficiency of up to 3.2 cd/A and 1.6%, respectively, when we utilized 4,4′-bis[4-(diphenylamino)styryl]biphenyl as a dopant. Meanwhile, the [N-(naphthalen-1-yl)-9,10-di(naphthalen-2-yl)-N-phenylanthra-cen-2-amine (DN-2-NPAA)] as a dopant material showed pretty good device performance, up to 5.2 cd/A and 2.2% (EQE), when we utilized 2-tert-butyl-9,10-di(naphth-2-yl)anthracene as a host.

非对称 9,10-二（2-萘基）蒽衍生物作为溶液处理蓝色荧光有机发光二极管的主体和发射体

摘要 已成功合成了一系列新的不对称蒽衍生物，用于溶液处理的蓝色荧光有机发光二极管（OLED）的发光层，可用作主体和掺杂剂。特别是，具有蒽部分且没有任何烷基链的新型合成蓝色荧光材料在普通有机溶剂中表现出高溶解性，这可能是由于其内部结构严重扭曲。由于其刚性的内部核心单元，它们还显示出中等高的热稳定性。使用这些新型可溶性蓝色荧光材料，我们创造了中等效率的溶液处理荧光 OLED。还有一种新的蒽衍生物[9-(9, 10-di(naphthalen-2-yl)anthracen-2-yl)-9H-咔唑 (DN-2-CzA)] 作为主体材料表现出中等高的效率和高达 3.2 cd/A 和 1.6% 的外量子效率分别是，当我们使用 4,4'-双[4-(二苯基氨基)苯乙烯基]联苯作为掺杂剂时。同时，作为掺杂材料的 [N-(naphthalen-1-yl)-9,10-di(naphthalen-2-yl)-N-phenylanthra-cen-2-amine (DN-2-NPAA)]当我们使用 2-叔丁基-9,10-二（萘-2-基）蒽作为主体时，器件性能良好，高达 5.2 cd/A 和 2.2% (EQE)。
