Highly efficient deep blue phenanthroimidazole fluorescent material by incorporating an adamantane moiety (AD-BPI) is designed and synthesized. AD-BPI exhibits excellent photophysical properties including a deep blue emission, high triplet energy level and photoluminescence efficiency, fine morphological and thermal stability, and ambipolar nature. Non-doped deep blue organic light-emitting diodes (OLEDs) following the construction of ITO (Indium–Tin Oxide)/TAPC (Bis [4‐[N, N‐di (4‐tolyl) amino] phenyl]‐cyclohexane, 30 nm)/AD-BPI (100 nm)/TPBi (1, 3, 5-tris (2-N-phenylbenzimidazolyl) benzene, 50 nm)/Liq (8-hydroxyquinolatolithium, 2 nm)/Al (100 nm) utilizing AD-BPI as emissive layer achieve the peak external quantum efficiency (EQE) of 5.8% with the CIE coordinates of (0.15, 0.07). Using AD-BPI as universal host, the corresponding green, yellow and red phosphorescent devices are also fabricated and exhibit the maximum EQEs of 23.3%, 16.7% and 19.1% accompanying with negligible efficiency roll-off under ultrahigh luminance. These experimental performances are intensely competitive with the recently reported advanced results of full-color OLEDs. It is the first demonstration of adamantane-based phenanthroimidazole molecule featuring as both host and emitter.

通过并入金刚烷部分（AD-BPI），设计并合成了高效的深蓝色菲并咪唑荧光材料。AD-BPI具有出色的光物理特性，包括深蓝色发射，高三重态能级和光致发光效率，良好的形态和热稳定性以及双极性性质。ITO（铟锡氧化物）/ TAPC（双[4- [N，N-二（4-甲苯基）氨基]苯基]苯基]-环己烷，30的构造之后的非掺杂深蓝色有机发光二极管（OLED） nm）/ AD-BPI（100 nm）/ TPBi（1、3、5-三（2-N-苯基苯并咪唑基）苯，50 nm）/ Liq（8-羟基喹啉锂，2 nm）/ Al（100 nm）利用AD -BPI作为发射层，其CIE坐标为（0.15，0.07），可达到5.8％的峰值外部量子效率（EQE）。使用AD-BPI作为通用主机，对应的绿色，黄色和红色磷光器件也被制造出来，它们的最大EQE分别为23.3％，16.7％和19.1％，并且在超高亮度下的效率衰减很小。这些实验性能与最近报道的全色OLED的先进结果极具竞争力。这是基于金刚烷的菲并咪唑分子兼具主体和发射体特征的首次演示。
