Supramolecular chemistry of substituted cucurbit[n]urils
Since the first example of substituted cucurbit[n]urils (Q[n]), decamethylcucurbituril (Me10Q), was reported in 1992, numerous substituted Q[n]s have been synthesized and studied. In this review article, we focus on the recognition properties of the substituted Q[n]s toward a variety of organic species as well as the coordination chemistry of substituted Q[n]s with different metal ions, including alkali/alkaline-earth metals, transition metals, and lanthanides. Applications of substituted Q[n]s, and the self-assembly processes affording mechanically interlocked molecules (MIMs) are also described. The main purpose of this review is to highlight important advances in the blossoming field of substituted Q[n]s, which will likely be of interest to researchers in supramolecular chemistry.
