Cyclo-oligo-(1 → 6)-β-D-glucosamine based artificial channels for tunable transmembrane ion transport.
Unimolecular ion channels were designed by functionalization of a new type of cyclic oligosaccharides, cyclo-oligo-(1 → 6)-β-d-glucosamines, with pentabutylene glycol chains. Their ion transporting activity was tuned by varying oligomericity. A halide selectivity sequence, Cl(-) > Br(-) > I(-) was observed.
