Abstract
Two pairs of CPL-active binaphthyl-pyrene emitters with good photophysical properties and excellent chiroptical performances can emit high brightness blue CP-EL. The theoretical calculation results show that R-/S-5 can form rigid helix π-π stacking in the aggregation state which may greatly contribute to gEL of CP-OLEDs.
摘要
两对具有良好光物理性质和优异手性光学性能的联萘芘发光体能够发出高亮度的蓝色圆偏振电致发光。理论计算结果表明，R-/S-5在聚集态下可形成刚性螺旋π-π堆积，这可能对圆偏振有机发光二极管的外量子效率有很大贡献。
