Abstract

NEW MATERIAL:3,4,9,10-Perylenetetracarboxylic acid diimide derivative of the formula wherein ϕ1, ϕ2 are eah alkyl, cycloalkyl, aralkyl, aryl, heterocyclic group.
USE: Dichroic coloring matter for liquid crystals, which develops a bright rose color with a high contrast.
PREPARATION: 3,4,9,10-Perylenetetracarboxylic acid anhydride and ϕ1NH2 or ϕ2NH2 are subjected to a dehydration-condensation reaction in a solvent such as dichlorobenzene or nitrobenzene with heating. This coloring matter exhibits absorption maximum wavelengths at 530±5 and 490±5.46, and develops a bright rose color in liquid crystals such as nematic liquid crystals and cholesteric/ nematic phase transition type liquid crystals.
