Description The supramolecular complex formed by partial inclusion of methylviologen in MeCB6 was described both in solution and in the solid state. The association constant of the complex was determined using 1H NMR and UV vis spectrophotometric titration. An extraordinary 2000 fold drop in the association constant of the complex was observed when pure water was replaced by 50 mM NaCl solution.
