## Description

- description: 'Charged pi-electronic systems with hydrophilic substituents form lyotropic
    chromonic liquid crystals (LCLCs) through charge-by-charge assembly driven by
    iπ–iπ interactions and hydrophobic effects.  In this study, the positions and
    numbers of triethylene glycol (TEG) chains in amphiphilic porphyrin AuIII complexes
    are tuned to control their assembly modes.  In combination with the π-electronic
    anion pentacyanocyclopentadienide (PCCp–), 5,15-TEG-aryl-substituted porphyrin
    AuIII complex generates lamello-columnar (Lamcol) phases via amphiphilic  iπ–iπ
    interactions and proximal interactions at the unsubstituted sites.  In the presence
    of water, the Lamcol phases, with lateral hydrophobic effects, exhibit transitions
    to nematic sheet (Nsheet) and isotropic sheet (Isosheet) phases depending on water
    content and temperature.  The Lamcol phases align macroscopically under a magnetic
    field, and scanning transmission electron microscopy (STEM) reveals monolayer
    sheet structures as key components of the LCLCs.  These findings demonstrate a
    controllable charge-by-charge strategy for designing π-electronic LCLCs with tunable
    structural and phase behaviors. '
