A fluorinated binaphthyl chiral dopant for fluorinated liquid crystal blue phases.

A 6,6′-fluorinated binaphthyl enantiomer, (R)-1, was applied as a chiral dopant to produce cholesteric blue phases (BPs). A fluorinated nematic liquid crystal doped with (R)-1 showed lower critical chirality to induce a BP and a larger temperature range of BPs than that doped with a conventional chiral dopant.
