Dual frequency liquid crystal (DFLC) compounds with high birefringence and ultra-low crossover frequency have been developed. The long conjugated rigid core structure gives these compounds a high birefringence (0.3-0.4) and ultra-low Debye relaxation frequency. Using these compounds we have formulated a new DFLC mixture, designated UCF-02, for operation at elevated temperatures. The birefringence of the mixture is greater than 0.3 at 25 degrees C and = 633 nm. Their initial ultra-low crossover frequency allows them to be used at elevated temperatures and significantly improves their utility.
