Abstract
Supramolecular capsules of THF and acid molecules inside cucurbit[6]uril have been prepared via [C2mim]Br route. The 1:1 ratio of host–guest complexes have been characterized by 1H NMR, thermal gravimetric analysis and elemental analysis in solution and in solid state. Two types of release have been observed in NaCl aqueous solution, including partial release of THF due to stronger binding and complete release of acid molecules (C3–C6) due to weaker binding.
