| Title of Invention | OPTICALLY ACTIVE COMPOUNDS |
|---|---|
| Abstract | A compound is of formula (I), in which: A1 to A4, E1 and E2 each independently represent hydrogen or an optionally-substituted hydrocarbon group; B1 and B2 each independently represent a single bond, an oxygen atom or an optionally-substituted hydrocarbon group; MG1 and MG2 each independently represent an optionally-substituted ring system; CG is a divalent or polyvalent chiral group. The optically active compound may be used as a doping agent for liquid crystals for a wide range of applications including solid state cholesteric filters for projection displays, circular polarisers, optical filters, etc. |
