Abstract

Climbing the cucurbit ladder: Cucurbit[6]uril dimers (connected gray cylinders; see scheme) were prepared by condensation of glycoluril hexamer with the appropriate tetraaldehydes. The self-assembly process between these dimers and oligoviologen compounds (blue) in water leads to a supramolecular ladder with the dimensions and molecular weight typical of small proteins.
