LC-1289 and E63 containing the studied CAd in very low concentrations (≤10–11 mol.%) have selective light reflection in the visible spectral region. The helical twisting power of the studied α,β-unsaturatedketones is determined by the combined influence of the anisotropy of polarizability of CAd molecules and specific features of their molecular shape.
