title: Facile synthesis of cucurbit[n]uril derivatives via direct functionalization: expanding utilization of cucurbit[n]uril.
abstract: A long-standing problem in cucurbituril chemistry is answered through the first direct functionalization of cucurbit[n]uril (CB[n]; n = 5-8)) leading to perhydroxyCB[n] which can be further modified to provide tailored CB[n] derivatives with desired functional groups and good solubility. Anchoring a CB[6] derivative on the surface and its potential application as a sensor are demonstrated. A CB[6] derivative forms nanospheres with possible use in protein and peptide drug delivery.
