Unimolecular ion channels were designed by functionalization of a new type of cyclic oligosaccharides, cyclo-oligo-(1 â 6)-β-D-glucosamines, with pentabutylene glycol chains. Their ion transporting activity was tuned by varying oligomericity. A halide selectivity sequence, Clâ > Brâ > Iâ was observed.

the bacteriallectinLecA with various valencies (from 2 to 4) and linkers. Evaluation of their binding properties towards LecA has been performed by a combination of hemagglutination inhibition assays (HIA), enzyme‐linked lectin assays (ELLA), and isothermal titration microcalorimetry (ITC). Divalentligands displayed dissociation constants in the sub‐micromolar range and tetravalent ligands displayed
