Self dynamic superstructures

The combined features of structural adaptation in a specific hybrid nanospace and of a dynamic supramolecular selection process make the dynamic-site membranes, presented in the third part, of general interest for the development of a specific approach toward nanomembranes of increasing structural selectivity. From the conceptual point of view these membranes express a synergistic adaptative behavior the addition of the most suitable alkali ion drives a constitutional evolution of the membrane toward the selection and amplification of a specific transport crown-ether superstructure in the presence of the solute that promoted its generation in the first place. It embodies a constitutional selfreorganization (self-adaptation) of the membrane configuration producing an adaptative response in the presence of its solute. This is the first example of dynamic smart membranes where a solute induces the preparation of its own selective membrane.

It is understood that nanotechnology is hunting for simple and versatile bottom-up self-assembly-based processes to assemble and (re)organize molecules and/or nanoparticles into well-defined functional superstructures in multiple dimensions over multiple length scales for many advanced technological applications. LCs are emerging as the viable systems for the dynamic self-assembly of nanomaterials in LC media as well as molecular dynamic self-assembly of LC molecules themselves. For example, it has been demonstrated that LCs enable reconfigurable and switchable...
