Abstract

Herein, we report the synthesis of a novel amphiphilic salt containing a number of hydrogen bond donating (HBD) and accepting (HBA) functionalities. This amphiphile has been shown to self-associate via hydrogen bond formation in a DMSO solution, confirmed through a combination of NMR, UV-Vis and dynamic light scattering and supported by X-ray diffraction studies. The combination of different HBD and HBA functionalities within the amphiphile structure gives rise to a variety of competitive, self-associative hydrogen bonding modes that result in the formation of 'frustrated' hydrogen bonded nanostructures. These nanostructures can be altered through the addition of competitive HBD arrays and/or HBA anionic guests. The addition of these competitive species modifies the type of self-associative hydrogen bonding modes present between the amphiphilic molecules, triggering the in situ formation of novel hydrogen bonded nanostructures.
