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.

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可提供最大电流效率和最大亮度，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。
