Abstract

The water soluble cucurbit[6]uril derivative CB*[6] forms a thermodynamically and kinetically stable host–guest complex with xenon in water, the binding affinity of which is about 3 × 10³ M⁻¹, comparable to those of cryptophanes, suggesting that it may serve as an effective molecular “carrier” for ¹²⁹Xe NMR-based biosensors.
