Design and synthetic engineering of OMSs

Sustainable synthesis of elementary bricks and study of property / structure relationships that govern self-assembly phenomena.

This thematic is centered on the design and synthesis of organized molecular systems, based on functional organic molecules which are real building blocks that self-assemble on the mesoscopic scale.
All these systems constitute a library in which to pick up to give tunable systems suitable for the chosen area of application. With a strong emphasis on sustainable chemistry, the synthetic challenge will be to follow the principles of molecular economy, as well as to use natural renewable resources, and bio-based and bio-inspired molecules.

Examples of biosourced or bioinspired architectures, DNA, lipopeptide, and amphiphilic dendrimer derived from sugars

A better understanding of the driving forces of self-assembly -in order to control them- is one of our main targets. The final aim is to establish structure/aggregation correlations, and therefore to conceive tunable systems, which can be used for various applications.

In parallel to the standard physico-chemical studies that are usually run in aqueous medium, the self-assembly of our systems is also studied in non-conventional structured media. The objective is to understand and to rationalize the formulation of these OMSs in these media.
