title: Cucurbit[n]uril analogues.
abstract: [structure: see text] Cucurbits come in a variety of sizes, shapes, and colors. We present a building block approach that allows the tailor-made synthesis of CB[5], CB[6], and CB[7] analogues whose sizes, shapes, and colors differ from those of the known CB[n].
