Strong CPL of achiral AIE-active dyes induced by supramolecular self-assembly in chiral nematic liquid crystals (AIE-N*-LCs).

Chiral binaphthyl enantiomers (Guest 1) were doped into commercial nematic liquid crystals (N-LCs, Host E7) to form chiral nematic liquid crystals (N*-LCs). The new ternary AIE-N*-LCs prepared by introducing four achiral AIE dyes (Guest 2) into N*-LCs can give rise to strong CPL responses with high luminescence dissymmetry factor (gem) values of up to1.42.
