prepared as an anion receptor which contained eight NHhydrogenbonds donors. Two indolocarbazole units were coupled through a butadiynyl linker to allow for helical folding of the resulting dimer by intramolecular hydrogen bonding and dipole–dipole attractions as proven in the 1H NMR spectroscopy. The dimer was found to bind anions (Cl− , Br− , N3 − , AcO− , and ) by multiple hydrogenbonds in 10% (v/v)
