      abstract     = {Crown ether–amino acid hybrids represent a promising
                      class of amphiphilic molecules combining ion recognition
                      with self-assembly capabilities. Despite extensive studies
                      on their binding properties, the influence of inorganic salt
                      complexation on their liquid crystalline behaviour remains
                      underexplored. Here we synthesized amphiphilic [18]-crown-6
                      derivatives of L-dihydroxyphenylalanine and
                      tetrahydroisoquinoline analogues, systematically
                      investigating the effects of alkyl chain length and salt
                      type on mesophase formation. Complexation with various salts
                      induced liquid crystalline phases, transitioning from
                      smectic A to columnar hexagonal structures as anion size and
                      alkyl chain length increased. Structural analyses and
                      electron density mapping revealed assembly into charged
                      superdiscs forming columnar stacks with tunable ion
                      channels. Broadband dielectric spectroscopy highlighted
                      differences in molecular mobility and conductivity linked to
                      molecular design. These findings establish salt complexation
                      as a key strategy to control self-assembly and ion transport
                      in crown ether–amino acid hybrids, advancing their
                      potential in responsive soft materials and ion-conductive
