"lyotropic chromonic liquid crystal assembly through iπ–iπ interactions (stabilized by electrostatic/ dispersion forces)... self-assembling molecules into organized structures... amphiphilic charged π-electronic systems... ordered arrangement of 1au⁺ stacked with PCCp⁻ anion via iπ–iπ interactions... achieved (1) horizontal orientation under static magnetic field, (2) vertical orientation under rotating magnetic field, (3) orientation changed in response to temperature, (4) ferroelectric control”
