TLDR
Cucurbit[n]urils have become key units in various self-organizing and stimulus-controlled assemblies, as well as in advanced materials and drug carriers.Abstract:
This review highlights the past six year advances in the blossoming field of cucurbit[n]uril chemistry. Because of their exceptional recognition properties in aqueous medium, these pumpkin-shaped macrocycles have been generating some tremendous interest in the supramolecular community. They have also become key units in various self-organizing and stimulus-controlled assemblies, as well as in advanced materials and drug carriers. The scope of this review is limited to the main family of cucurbit[n]urils (n = 5, 6, 7, 8, 10). The reader will find an overview of their preparation, their physicochemical and biological properties, as well as their recognition abilities towards various organic and inorganic guests. Detailed thermodynamic and kinetic considerations, as well as multiple applications including supramolecular catalysis are also discussed.read more

Phototautomerization in pyrrolylphenylpyridine terphenyl systems.
TL;DR: The pyridinium salt 4H(+) forms a stable complex with cucurbit[7]uril (CB[7]) with 1:1 stoichiometry with strong transient absorption maxima at 390 nm and the decay of 4-T followed exponential kinetics with a rate constant of 4.2 × 10(6) s(-1).

An ‘in-water’ halogen-ion compatible “click” catalyst for cucurbituril guest ligation
TL;DR: An ‘in-water’ halogen-ion compatible copper catalysed azide–alkyne cycloaddition (CuAAC) catalyst, tris[1-(3-hyroxypropyl)-1H-1,2,3-triazol-4-yl]methanol·CuCl (THPTM·Cl), was designed for CB guest ligation and verified its applicability for the construction of CB-based supramolecular architectures.

TL;DR: Temperature-dependent 57Fe Mössbauer effect spectroscopic studies were carried out on ferrocene, 1,1'-dimethylferrocene and ferrocenium hexafluorophosphate guest species in cucurbit[n]uril inclusion complexes, suggesting that the organometallic guest molecules do not interact significantly with the host environment over the experimental temperature range.

Self-assembly of size-tunable supramolecular nanoparticle clusters in a microfluidic channel
TL;DR: In this article, a microfluidic nanoparticle cluster formation between ligand-functionalized silica nanoparticles, dendrimers, and poly(ethylene glycol) (PEG) stopper molecules is induced by the ternary charge-transfer complex formation between cucurbit[8]uril, methyl viologen and naphthol.

The cucurbit[n]uril family
TL;DR: In 1981, the macrocyclic methylene-bridged glycoluril hexamer (CB[6]) was dubbed "cucurbituril" by Mock and co-workers because of its resemblance to the most prominent member of the cucurbitaceae family of plants--the pumpkin.
