Self-assembly

Animated by Denis Frath

In recent years, the concept of self-assembly has become central in many of the research activities carried out within the three axes of the laboratory. This theme brings together scientific activities that aim to organize elementary blocks into larger-scale structures. These blocks can be small molecules, polymers or nanoparticles, but whether it is supra-molecular chemistry, ionic liquids or the assembly of nanoparticles, the idea is to better understand and apprehend the forces. weak between the base units to bring out an order at more or less long range. The aim of this research is to bring out original properties such as a particular rheological behavior or optical properties resulting from coupling between the elementary blocks. This theme uses common tools, both experimental and theoretical, and targets a varied range of applications ranging from miniaturization in molecular electronics, to self-repairing materials, including vectorization or the controlled uptake and release of molecules. In the near future, we would like to direct this research towards systems responding to external stimuli such as light or an electrochemical signal.
