Regulated assemblies and anion responsive vesicles based on 1,3-alternate oxacalix[2]arene[2]triazene amphiphiles†
Abstract
Regulated assemblies from vesicles to micelles based on 1,3-alternate oxacalix[2]arene[2]triazine amphiphilic molecules were reported. The vesicular entities were responsive to anions and followed the selectivity in the order NO3− > Cl− > Br− > ClO4−, driven by cooperative anion–π interactions and hydrogen bonding.
