The object of this research was to establish binding constant (K) values for the complexation of cucurbit[7]uril (CB7) with the organic dyes methyl viologen, acridine orange, and 4,4'-bipyridine. UV-Vis absorption as a function of temperature and host-guest molar ratio was studied and compared to quantum chemical and molecular mechanics calculations.
