Six tert-butyls modified naphthyl derivative (2,6-di-tert-butyl-1,5-bis-(3,5-di-tert-butyl-phenyl)-naphthalene (N(dtb)₄) was synthesized and tested for host and guest materials in organic light-emitting diodes (OLEDs). Blue OLED using N(dtb)₄ as a host and an emitter DSA-PH as a guest reaches an efficiency of 11.52 cd·A⁻¹ (maximum external quantum efficiency 7.8 % and maximum power efficiency 10.33 lm·W⁻¹). In addition, for the OLED with N(dtb)₄ being a guest, we find that the concentrations of N(dtb)₄ will also affect the performance of the OLED, among which ADN: 5 wt.% N(dtb)₄ has higher efficiency, and the maximum current efficiency, external quantum efficiency (EQE) and power efficiency of the device reach 3.75 cd·A⁻¹, 3.93 % and 3.36 lm·W⁻¹, respectively. We also investigated the pure N(dtb)₄ -based ultraviolet OLED (UV-OLED), and achieved the maximum EQE of the device is 1.12 %. These results indicate that N(dtb)₄, a novel synthesized fluorescent organic material, has great potential applications in OLEDs and accordingly advancing lightings and displays.

合成并测试了六种叔丁基改性萘基衍生物（2,6-二叔丁基-1,5-双-（3,5-二叔丁基-苯基）-萘（N(dtb) ₄）用于有机发光二极管 (OLED) 中的主体和客体材料。使用 N(dtb) ₄作为主体和发射极 DSA-PH 作为客体的蓝色 OLED的效率达到 11.52 cd·A ^-1（最大外量子效率） 7.8 % 和最大功率效率 10.33 lm·W ^-1 . 此外，对于以 N(dtb) ₄为客体的 OLED ，我们发现 N(dtb) ₄的浓度也会影响 OLED 的性能，其中ADN：5 wt.% N(dtb) ₄具有更高的效率，器件的最大电流效率、外量子效率(EQE)和功率效率分别达到3.75 cd·A ^-1、3.93 %和3.36 lm·W ^-1。我们还研究了纯 N(dtb) ₄基紫外 OLED (UV-OLED)，并实现了器件的最大 EQE 为 1.12%。这些结果表明，N(dtb) ₄是一种新型的合成荧光有机材料，在OLED 中具有巨大的应用潜力，并因此推动了照明和显示器的发展。
