One important aspect of modern chemistry is directed towards the synthesis of complex nanomolecules that exhibit specific properties for applications in materials science and biology. However, the preparation of complex nanostructures combining the required functional groups remains often difficult and requires a large number of synthetic steps thus limiting both their accessibility and applicability. Our research group has shown that the preparation of easily accessible nanoscaffolds allowing for the grafting of one or more molecular entities is an appealing strategy to generate sophisticated nanomolecules.1 Overall, one of our main concerns is to increase the complexity of the molecular structures without increasing the synthetic difficulties. This is an important challenge for synthetic organic chemistry in general. As part of this research, we became interested in pillar[5]arene and pillar[5]arene-based rotaxanes as compact scaffolds for the construction of nanomaterials.2 Our latest advances in this particular field will be presented.
Speaker bio:
Jean-François Nierengarten studied biochemistry and chemistry at the University of Strasbourg, France, and received his doctoral degree under the supervision of Jean-Pierre Sauvage and Christiane Dietrich-Buchecker in Strasbourg (1994). He worked as a postdoctoral fellow with François Diederich at the ETH-Zürich, Switzerland (1994-1996). He obtained a CNRS researcher position in 1996. He is currently Directeur de Recherche at the CNRS (DR1) and head of the Laboratoire de Chimie des Matériaux Moléculaires (University of Strasbourg and CNRS). His research focuses on the chemistry of fullerenes for applications in materials science and biology. Other research interests are in the area of dendrimers, luminescent transition metal complexes, macrocyclic compounds, porphyrins and pi-conjugated systems. He is a fellow of the Royal Society of Chemistry (RSC) and has been awarded the bronze medal of the CNRS in 2001, the SFC-ACROS prize from the Organic Chemistry Division of the French Chemical Society in 2004, the Grammaticakis-Neuman Prize from the French Academy of Science in 2007, the Catalan-Sabatier Prize from the Spanish Royal Society of Chemistry in 2013, the prize from the Coordination Chemistry Division of the French Chemical Society in 2018, the prize from the Organic Chemistry Division of the French Chemical Society in 2019 and the silver medal of the CNRS in 2019. He has published over 270 papers and 17 book chapters. He is a member of the Advisory Board of Chemical Communications and chairman of the Editorial Board of Chemistry-a European Journal.
