A method is provided for using twisted acenes, and more particularly to configurationally stable twisted acenes that are imbedded into the structure of [7]helicene at the fulcrum ring to form useable material structures. The helicene propagates its chiral nature into the acene, while acting as a locking mechanism to thermal racemization. These doubly-helical compounds are part of a new homologous series of polycyclic aromatic hydrocarbons, namely the [7]helitwistacenes. Such [7]helitwistacenes have utility as materials suitable for forming a circularly polarized organic light emitting diode (CP-OLED) for direct emission of circularly polarized (CP) light for the fabrication of high efficiency electronic displays.
本发明提供了一种使用扭曲烯的方法,特别是将构型稳定的扭曲烯嵌入支点环上的 [7]helicene 结构中,以形成可用的材料结构。螺旋烯将其手性传播到烯中,同时作为热外消旋化的锁定机制。这些双螺旋化合物属于多环
芳烃的新同源系列,即[7] helitwistacenes。这种[7] helitwistacenes 材料适用于形成圆偏振有机发光二极管(CP-OLED),可直接发射圆偏振光,用于制造高效电子显示器。
