具有聚集诱导的发射和热活化的延迟荧光性质ECPPTT、ECDPTT新型化合物的合成
两种基于苯乙烯,咔唑和9,9',10,10'-四氧化蒽的新型化合物的合成,聚集诱导的发射和热活化的延迟荧光性质
在本文中,通过结合四苯基/三苯基乙烯(TPE / TrPE),咔唑基和噻吩-9,9,10,10-四氧化物单元,设计并合成了两种发光材料ECPPTT和ECDPTT。ECPPTT和ECDPTT具有明显的AIE和TADF功能,并分别在240°C和262°C的薄膜中显示出良好的热稳定性。
制备了使用ECPPTT和ECDPTT作为发射层的非掺杂有机发光二极管(OLED),它们呈现出蓝绿色和绿色发射色,其峰值分别在494和517 nm处。基于ECPPTT的非掺杂OLED具有3.437 cdA -1的良好峰值EL效率和10090cdm -2 ;
而用ECDPTT制造的非掺杂OLED可提供电流效率和亮度,分别为2.478 cdA -1和7561cdm -2。
这些结果证明了组合AIE和TADF单元设计新分子的可行性。
具有聚集诱导的发射和热活化的延迟荧光性质ECPPTT、ECDPTT新型化合物的合成
In the text, two luminescent materials ECPPTT and ECDPTT, have been designed and synthesized by integrating tetraphenyl/triphenyl-ethene(TPE/TrPE), carbazole group and thianthrene-9,9,10,10-tetraoxide unit. ECPPTT and ECDPTT possess obvious AIE and TADF capabilities, and show good thermal stability in their thin film of 240 °C and 262 °C, respectively. Non-doped organic light emitting diodes(OLED) using ECPPTT and ECDPTT as emission layer are prepared and exhibit blue-green and green emission color with peaks at 494, 517 nm, respectively. The non-doped OLED based on ECPPTT provides good peak EL efficiencies of 3.437 cdA-1 and 10090cdm-2; while non-doped OLED fabricated with ECDPTT affords a maximum current efficiency and a maximum luminance of 2.478 cdA-1 and 7561cdm-2. These results have demonstrated the feasibility of combing AIE and TADF units to design new molecules.
