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

Synthesis, cytotoxicity and cucurbituril binding of triamine linked dinuclear platinum complexes.
TL;DR: The results show that the protonated secondary amine in CT033 acts as a barrier to encapsulation, with the Q[7,8] being positioned over only one propyl-arm at a time, which suggests that the insertion of a positive charge into the linking ligand may not, per se, be responsible for the higher cytotoxicity generally observed for dinuclear platinum complexes linked by polyamines.
