摘要:
通过将三聚苯乙烯(TPV)通过中心苯环的苯基-苯基键连接起来,构建了一种新的结构寡聚(苯乙烯-苯乙烯)。 所得TPV二聚体在固态下表现出微弱的分子间相互作用和强烈的蓝色光致发光,以及高达250°C的高相变温度。基于这些材料的有机发光二极管(OLED)显示蓝色发射,具有低开启电压(约3 V),最大亮度接近2000 cd m-2,效率高达1.6 cd A-1。

Building a new structual oligo(phenylenevinylene) by linking trimeric phenylenvinylene (TPV) through the phenyl–phenyl bond of a central phenylene ring was reported. The resultant TPV dimers exhibit weak intermolecular interactions and intense blue photoluminescence in the solid state as well as high phase transition temperatures up to 250 °C. Organic light-emitting devices (OLEDs) based on these materials display blue emission with low turn-on voltage (about 3 V), maximum luminance approaching 2000 cd m−2 and efficiency up to 1.6 cd A−1.
