The AM2N team allows, by regrouping molecular chemists, to contribute by an original way in federative topics of the Institute Charles Gerhardt. Themes of the team, centered on the elaboration of molecular architectures, can develop in perfect synergy with group. It is clear that tools and methods developed by molécularistes allow the building of more and more complex buildings, and that hétéroéléments plays a role of first plan particularly in materials various ownership. Competences and knowledges of the team find in this domain of targets, a promotion and an enrichment. We have broad capacities particularly to work out, on one hand, molecular objects based on hétéroéléments and to control, of which other part, three-dimensional assemblages being to be solid par forerunners’ judicious choice, carrying functionalities or having adapted structures.
