Abstract
A dye composition dissolvable within a liquid crystal host device (including: polymer dispersed liquid crystal, polymer network liquid crystal, polymer stabilized liquid crystal, liquid crystal displays and similar devices), comprising eutectic mixtures of dichroic metallomesogen molecules. The aforesaid metallomesogen molecules comprise chromophore groups synthesized by physical and chemical mixing methods.
