- Title:
- Kinetics of Formation of the Host–Guest Complex of a Viologen with Cucurbit[7]uril
- Description:
- Host–guest complexation between the dicationic viologen 1-tri(ethylene glycol)-1′-methyl-m-xylyl-4,4′-bipyridinium and cucurbit[7]uril (CB7) was studied at pH = 4.5 in water. The stability constants of the mono- and bis-CB7 adducts were determined at 25 °C by UV–vis spectroscopy. Stopped-flow kinetic experiments were performed to measure the formation and dissociation rate constants of the monoadduct: k1 = (6.01 ± 0.03) × 106 M–1 s–1 and k–1 = 52.7 ± 0.4 s–1, respectively. Possible mechanisms of complexation are discussed in view of the kinetic results.
