A series of pyrene-centered starburst oligocarbazoles (1–3) have been synthesized and well characterized. Based on photophysical, thermal and electrochemical studies in solutions and as thin films, all starburst molecules reveal a sky blue emission with a high efficiency (ΦF = 0.99 − 0.81) and excellent thermal and electrochemical stabilities. As OLED materials, these superior properties are helpful to enhance device stability and lifetime.
我们合成了一系列以芘为中心的星爆低聚咔唑(1-3),并对其进行了充分表征。基于溶液和薄膜中的光物理、热和电化学研究,所有星爆分子都能发出天蓝色的光,具有高效率(ΦF = 0.99 - 0.81)和出色的热稳定性和电化学稳定性。作为有机发光二极管材料,这些优异的特性有助于提高设备的稳定性和使用寿命。
