Kinetics of dye-dendrimer electrostatic self-assembly
In this experiment, we will investigate the formation kinetics of supramolecular nanostructures by electrostatic self-assembly, specifically the association of cationic dendrimers with an anionic light-responsive azo-dye. Over the last years, we have established electrostatic self-assembly as a powerful route to build defined nano-objects with a variety of sizes, shapes, and functionalities, including light-switchability. Yet, to fully exploit this strategy, not only knowledge of resulting structures but also a fundamental insight into assembly and structure-reformation mechanisms is needed. For this purpose, we will use time-dependent SANS to follow particle growth and shape development in the assembly process. We have optimized an assembly process so that it can be followed in the accessible time scale of SANS and will consider results in conjunction with DLS and SLS as well as ¿-potential measurements and UV-Vis spectroscopy to reveal charge status and dye-dye interactions on the molecular scale. This experiment is part of the ILL PhD project ¿Light-Tunable Structures by Self-Assembly: In-situ SANS Under Irradiation¿.
