Abstract
Tetrahydrothiophenocucurbit[5 and 6]uril has been synthesized from tetrathiophenoglycoluril diether, providing thioether functionality at the exterior equatorial position of the cucurbituril cage. This functionality has been investigated for chemical modification through sulfoxide formation and subsequent Pummerer rearrangement to the acetoxy derivative of the tetrahydrothiophenocucurbit[5]uril. Nanoparticles of Au and Ag were prepared in the presence of tetrahydrothiophenocucurbit[6]uril, which curiously led to the formation of nanoparticle chains, growing in length over days to weeks.

Abstract
Self-assembly is a phenomenon that governs molecular structural organization in nature, therefore raising research interest for the fabrication of novel nanomaterials with diverse applications in biocatalysis, biomedicine, material templating, and biosensor development. In this chapter we provide protocols for the development of supramolecular protein complexes based on host-guest interactions in the presence of the macrocyclic host, cucurbit[8]uril (CB[8]). CB[8] is reported to exhibit high binding affinity towards the tripeptide Phe-Gly-Gly (FGG), therefore it can be utilized as a selective adhesive of protein molecules, after fusion of FGG to an accessible protein surface.

Abstract
A novel triazolyl bridged cucurbituril (CB)-cyclodextrin (CD) dimer was synthesized via click reaction of monopropargyl modified octamethylcucurbit[6]uril and mono-6-azido-β-cyclodextrin. Moreover, it could form stable supramolecular inclusion complexes possessing efficient fluorescence resonance energy transfer, which benefited from the fact that CD and CB can bind amantadine- and pyridinium-containing fluorophores simultaneously. The supramolecular inclusion complex behaviors were investigated by NMR spectroscopy, UV-vis absorption, and fluorescence spectroscopy.
