Fluorescent liquid crystals : Hydrogen bonding of benzoic acids to azaaromatic receptor groups of diazadibenzoperylene fluorophores induces columnar liquid crystalline mesophases which are highly fluorescent. The structure of a mesogenic supermolecule generated in this way is shown on a background of a polarizing micrograph of the resulting liquid crystalline phase.
