Studies of the interaction of tetramethylcucurbit[6]uril and 5,5'-dimethyl-2,2'-bipyridyl hydrochloride.
The interaction between tetramethylcucurbit[6]uril (host) and 5,5'-dimethyl-2,2'-bipyridyl hydrochloride (guest) was studied by 1H NMR, X-ray crystallography, electronic absorption spectroscopy, fluorescence emission spectra and quantum chemistry calculations. This experimental-computational study that indicated the host can orientationally encapsulate the guest with a moderate association constant value. Computation qualitatively explained the split UV-visible absorption peak of the inclusion complex.
