Selective sulfate binding induces helical folding of an indolocarbazole oligomer in solution and solid state.
Hydrogen bonding to anions drives the helical folding of an indolocarbazole oligomer, thus resulting in an internal cavity with six NHs and two OHs for binding sulfate with high selectivity.
