Abstract
Abstract
The nomenclature ‘chromonic’ has been incorporated into the usual jargon of researchers to characterize lyotropic mixtures made of flat, aromatic molecules, with ionic parts on the periphery of the molecule. Differently from molecular aggregates formed by the hydrophobic/hydrophilic interactions between aliphatic molecules, as encountered in lyotropic liquid crystalline mixtures, the primary units in chromonics are the aromatic molecules (disc- or plank-like in shape). The molecular packing is favoured by pi-stacking interactions between flat molecules. They pile up in columns of different heights and the forces that drive this face-to-face adhesion of molecules are of enthalpic origin. The structure, phase diagrams, and physical properties of these mesophases are discussed.
