Supramolecular assemblies of polyrotaxane type : Synthesis and applications for future。

 

Supramolecular chemistry is at the origin of the smart supramolecular system syntheses. Supramolecular assemblies of polyrotaxane type could be symbolized as a pearl necklace. The pearls are cyclic molecules which could move along the polymer chain blocked at each ends by large groups avoiding “pearl” dethreading. This type of structure is recognized as confering a dynamer character with unexpected properties. The understanding of the pseudo-polyrotaxanes properties has led to optimize a new synthetic pathway with a high 95% yield, higher than yields ever reported in the literature giving hardly more than 20%. This result opens more economical uses of these new assemblies for applications with adaptative mechanical properties; several examples of new applications will be discussed: for instance new water soluble polyrotaxanes have been synthetized. Polyrotaxane synthesis based on conductive polymer has been developed by a collaboration with the Iasi group in Roumania. In another example, the discovery of the outstanding mechanical properties of slidding gels of polyrotaxanes has made possible patent filing with the Japanese society Menicon about a new polyrotaxane synthesis.

 

Nathalie JARROUX

Assistant Professor, was partner of several research projects (ACI lipo-jet) and private foundings by industrial collaboration. She has led a team of Polymer Materials at Interfaces since 2003, comprising biologists, physicists and chemists in CNRS of Thiais and Evry LAMBE since 2010. She made a significant contribution to control the supramolecular assemblies based on polymer by yield optimization of polyrotaxane syntheses and mimicking the motility of the Listeria bacteria. In 2012, she was awarded for her Research Habilitation then received the qualification for a Full Professor position in 2013. Since 2013, she is co-leader of the LAMBE’s staff 4.
