TLDR
A wide range of reaction conditions are examined that include the effects of acid type, acid concentration, reactant concentrations, and temperature to both probe the mechanism and optimize the yields of isolated cucurbit[n]urils, where n = 5-10.Abstract:
The acid-catalyzed synthesis of cucurbit[n]urils from formaldehyde and glycoluril is poorly understood. In this paper, we examine a wide range of reaction conditions that include the effects of acid type, acid concentration, reactant concentrations, and temperature to both probe the mechanism and optimize the yields of isolated cucurbit[n]urils, where n = 5−10. A mechanism for the formation of these cucurbit[n]urils is presented. Individual cucurbit[n]urils were unambiguously identified in reaction mixtures using ESMS and 13C NMR.read more

Thermoresponsive Interplay of Water Insoluble Poly(2-alkyl-2-oxazoline)s Composition and Supramolecular Host–Guest Interactions
TL;DR: Interestingly, the large number of hydrophobic nonyl units across the polymer chain induced the formation of kinetically-trapped nanoparticles in solution that further agglomerate into larger aggregates at a temperature that is dependent on the polymer composition and the cavitand type and concentration.

Dual-cross-linked dynamic hydrogels with cucurbit[8]uril and imine linkages
TL;DR: The strategy of dual cross-linking of phenylalanine modified ε-polylysine was investigated by enhancing the performance of dynamic hydrogels and demonstrated a higher mechanical strength, better extensibility and faster self-healing rate.
