【摘要】：我们以钯为催化剂、通过一步交联耦合反应合成了一系列以螺[芴-9,9′-氧杂蒽](SFX)为基本构建单元的新型主体材料,这些材料具有较高的三线态能级和产率,可用作蓝色磷光材料的主体。接着,以这些材料和空穴传输型材料TAPC作为双主体、以FIrpic为发光客体,制作了蓝色磷光有机发光器件(PHOLED)。SFX主体材料可以向FIrpic提供有效的能量转移,而TAPC可以提高发光层的空穴迁移率、同时降低器件工作电压,因此我们制备的蓝色发光器件具有良好的性能。其中,以TAPC:PF-SFX和TAPC:C8OPF-SFX为双主体的两个PHOLED,最大电流效率和亮度分别达到22.56、25.93 cd?A~(-1)和6421、6196 cd?m~(-2)。上述实验结果表明,只存在C、H、O时,SFX是构建高效蓝色磷光主体材料的有效结构单元。
[Abstract]:Using palladium as catalyst, a series of novel host materials were synthesized by one-step cross-linking coupling reaction. A series of novel host materials with spiro-fluoren-9na-oxoxy-anthracene (SFX) as basic building units were synthesized. These materials have high three-wire energy levels and yields. It can be used as the main body of blue phosphorescence material. Then, the blue phosphorescence organic light-emitting device (PHOLED). SFX) is fabricated by using these materials and hole transport material TAPC as double host and FIrpic as luminous object, which can provide effective energy transfer to FIrpic. TAPC can improve the hole mobility of the luminescent layer and reduce the operating voltage of the device, so the blue luminescent device we prepared has good performance. The maximum current efficiency and luminance of the two PHOLED, with TAPC:PF-SFX and TAPC:C8OPF-SFX as dual hosts are 22.56 cd?A~ (-1) and 6121 cd?m~ (-2), respectively. The experimental results show that SFX is an effective structure unit for the construction of high efficient blue phosphorescence main material.
