## Description

- description: 'In this study, a new assembly strategy for lyotropic chromonic liquid
    crystals (LCLCs) is proposed using iπ–iπ interactions, mainly comprising electrostatic
    and dispersion forces, between charged π-electronic systems to form stacking structures
    supported by the hydration of triethylene glycol (TEG) units.  Meso-TEG-aryl-substituted
    porphyrin AuIII complex, an amphiphilic π-electronic cation, showed diverse states
    and assembly modes in ion pairs depending on the coexisting counteranions.  The
    PCCp– ion pair formed a hexagonal columnar (Colh) LC phase based on a charge-by-charge
    assembly, suggesting the formation of an ordered arrangement of charged π-electronic
    systems through iπ–iπ interactions, with reduced interactions between the TEG
    chains.  Furthermore, in the presence of water, LCLC behaviors in the Colh and
    nematic columnar phases according to the amount of water were observed for the
    PCCp– ion pair via iπ–iπ interactions.  Magnetic-field-induced orientation of
    the charge-by-charge columnar structures upon dehydration was observed.  Furthermore,
    single-stranded charge-by-charge columnar structures, as components of the LCLCs,
    were observed using transmission electron microscopy (TEM). '
