A sensor system to probe the propensity of carbohydrates to induce helical structures through long-range hydrogen bonds, based on a C(2)-symmetric xylylene bis(thiourea) arrangement, is reported; the formation of intermolecular complexes with benzoate anion promotes helix uncoiling, the free energy of the process being related to helix stability.
