Abstract: Im Jahre 1981 tauften Mock und Mitarbeiter das makrocyclische methylenverbruckte Glycoluril-Hexamer (CB[6]) auf den Namen “Cucurbituril” – da ihre Form einem Kurbis ahnelt, dem bekanntesten Mitglied der Cucurbitaceae-Familie in der Pflanzenwelt. In den folgenden Jahren wurden die grundlegenden Bindungseigenschaften von CB[6] – die hohe Affinitat und Selektivitat sowie der Einschluss von Gasten – in bahnbrechenden Arbeiten der Gruppen von Mock, Kim und Buschmann aufgezeigt; es folgten Anwendungen in der Wasseraufarbeitung, kunstlichen Enzymen und molekularen Schaltern. Erst vor kurzem wuchs die Cucurbit[n]uril-Familie um Homologe (CB[5]–CB[10]), Derivate, Verwandte und Analoga, sodass sie nun die Molekulgrosen von α-, β- und γ-Cyclodextrinen umfasst und ubersteigt. Auch die Formen, Loslichkeiten und chemischen Funktionalitaten konnen inzwischen durch spezielle Synthesen den Erfordernissen angepasst werden. Durch diese Eigenschaften sind die Cucurbiturile pradestiniert fur eine zentrale Rolle in molekularer Erkennung, Selbstorganisation und Nanotechnologie. Dieser Aufsatz stellt Synthesen, Erkennungseigenschaften und Anwendungen dieser einzigartigen Makrocyclen vor.

Bambus[6]uril
TL;DR: A macrocyclic hexamer, the structure of which is reminiscent of part of the bamboo-plant stem, was directly prepared by the condensation of a glycoluril derivative and formaldehyde to produce macrocycle bound halide anions with high affinity and selectivity.

High and Highly Anisotropic Proton Conductivity in Organic Molecular Porous Materials
TL;DR: The high and highly anisotropic proton conductivity in cucurbituril-based organic molecular porous materials, which can be modulated by the nature and amount of guest acid molecules present in the channels, is presented.

Supramolecular Peptide Amphiphile Vesicles through Host–Guest Complexation
TL;DR: A supramolecular approach to form the peptide amphiphile by connecting two building blocks through a non-covalent interaction would represent a major advance, especially in designing stimuliresponsive systems capable of being targeted by specific triggers.

Cucurbit[8]uril-based supramolecular polymers.
TL;DR: The current state of play in the fabrication of -based supramolecular polymers, which mainly include small-molecule-based supramsolecularpolymers and polymer-based Supramolecules, are summarized as a good example of the marriage between the supramolescular chemistry of cucurbiturils and polymer science.
