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.
