摘要：Dehydroabietic acid triarylamine (DTPA) synthesized from renewable natural rosin is an excellent hole-transporting material but suffers aggregation-caused quenching in the solid state. Herein, two new biomass-based AIE luminogens (BioAIEgens) labeled as DTPA-TPE and 2DTPA-TPE were synthesized via DTPA attaching to Tetraphenylethene(TPE). Their aggregates in poor solvents and thin films emit intensely with fluorescence quantum yields up to 67.4%. DTPA AIEgens exhibit superior thermal and morphological stability, showing high thermal degradation ( T 5d up to 412.0 °C) and glass transition ( T g up to 150.8 °C) temperatures. Electroluminescence (EL) devices with compounds used as emitting layers (EMLs) or used as EMLs and hole-transporting layers (HTLs) were constructed. The device with 2DTPA-TPE as EML exhibits the best performance (turn-on voltage of 2.4 V, maximum luminance of 12414 cd m ?2 , current efficiency of 6.2 cd A ?1 , and power efficiency of 6.5 lm W ?1 ). The devices without the HTL (NPB) exhibit performances comparable to or better than those of the devices with NPB. These results indicate that these compounds are promising luminescent materials for non-doped organic light-emitting diodes. ? 2022, The Authors. All rights reserved.
