Abstract

Abstract:

One guest 1-butyl-4,4'-bipyridinium bromide(BV⁺) was designed and synthesized, while supramolecular assemblie of tetramethylcucurbit[6]uril(TMeQ[6]) with the guest BV⁺ was investigated by ¹H NMR and UV-Vis absorption spectra, thermogravimetry analysis and X-ray crystallography in details. The experimental results showed that TMeQ[6] can preferred encapsulate the butyl moiety of the 1-butyl-4,4'-bipyridinium guest in its hydrophobic cavity to form inclusion complexes with a ratio of 1:1 in the aqueous solution and solid state. This observation contributes to a deeper understanding in molecular recognition, design and construction of novel molecular machines.

Key words: TMeQ[6], 1-Butyl-4,4'-bipyridinium bromide, Supramolecular self-assembly
