New highly twisted and rigid blue materials composed of anthracene with xylene as the core unit and either naphthalene or phenyl end units were synthesized. Non-doped devices using BDNA displayed 5.26% maximum external quantum efficiency with CIE color coordinates (x, y: 0.159, 0.072).
我们合成了以二甲苯为核心单元、萘或苯基为末端单元的新型高扭曲刚性蓝色材料。使用 BDNA 的非掺杂器件显示出 5.26% 的最大外部量子效率,CIE 色坐标(x, y: 0.159, 0.072)。
