Title

In situ analysis of structural changes in ionic nanoassemblies upon irradiation

Abstract

Complex macromolecular structures that can respond to external triggers can be obtained by self-assembly through non-covalent interactions. Recently we have introduced electrostatic self-assembly as a new concept for the formation of well-defined light-triggerable supramolecular nano-objects in aqueous solutions. So far, only start and end structure have been characterized in detail. Goal of this experiment is to fundamentally understand the structural rearrangement processes. Focus will be to study the light-induced structural changes after an initial irradiation and during a 20 min irradiation in a time-resolved manner. Results will allow detecting particle coagulation, growth and shape changes in a dynamic manner.
