Abstract
Several cyano and fluoro bis-tolane liquid crystals were synthesized and th eir physical properties evaluated. Some of these highly conjugated liquid c rystals possess birefringence larger than 0.5 in the visible region. Adding 10% of a binary bis-tolane mixture to a cholesteric display enhances the b rightness by more than 20%.
