ABSTRACT:
Methine 4-nitro-arylidene dyes having certain substituents in the 2 position of the arylidene group are found to be pleochroic and to form guest-host combinations with dielectrically positive anisotropic nematic liquid crystals. These combinations are employed in electro-optical display devices.
