有机半导体中高载流子迁移率和高发光的集成是具有挑战性的。然而，有机电致发光晶体管和有机电泵激光器需要这种材料。本文报道了一种新型有机半导体--2，6-二苯基菲，它不仅具有高的发射效率，单晶的绝对荧光量子产率为41.2%，而且具有高的载流子迁移率，单晶迁移率为34 V−1 S−1。基于DPA的有机电致发光二极管(OLED)具有高达6,627 Cd m−2的发光亮度和2.8 V的开启电压。高迁移率、强荧光的有机半导体是光电子器件的必备材料。在这里，刘等人。展示了一种有机半导体，2，6-二苯基菲，满足这两个要求，迁移率为34 cm~2 V−1 S−1和6,627 Cd m−2在2.8 V的开启电压下发射。
The integration of high charge carrier mobility and high luminescence in an organic semiconductor is challenging. However, there is need of such materials for organic light-emitting transistors and organic electrically pumped lasers. Here we show a novel organic semiconductor, 2,6-diphenylanthracene (DPA), which exhibits not only high emission with single crystal absolute florescence quantum yield of 41.2% but also high charge carrier mobility with single crystal mobility of 34 cm2 V−1 s−1. Organic light-emitting diodes (OLEDs) based on DPA give pure blue emission with brightness up to 6,627 cd m−2 and turn-on voltage of 2.8 V. 2,6-Diphenylanthracene OLED arrays are successfully driven by DPA field-effect transistor arrays, demonstrating that DPA is a high mobility emissive organic semiconductor with potential in organic optoelectronics. Organic semiconductors with high mobility and strong fluorescence are necessary for optoelectronic devices. Here, Liu et al. show an organic semiconductor, 2,6-diphenylanthracene, satisfying both requirements with mobility of 34 cm2 V−1 s−1 and emission of 6,627 cd m−2 at a turn-on voltage of 2.8 V.
