title: Cucurbiturils substituted on the methylene bridge.
abstract: Cucurbit[6]uril (CB[6]) with a substituent attached solely to one methylene bridge was prepared for the first time. The monosubstituted CB[6] undergoes self-assembly to form a cyclic tetramer in the solid state. The affinity of the monosubstituted CB[6] to a series of alkylammonium salts was measured revealing a minor effect of the substituent on the binding properties of the macrocycle.
