Summary of scientific research
Jean-Marie Lehn received his Doctorat-ès-Sciences in 1963 from the University of Strasbourg working in the laboratory of Guy Ourisson. The following year he joined the group of Robert Burns Woodward at Harvard University, where he participated in the total synthesis of vitamin B12. On his return to Strasbourg he started to work in areas on the frontier between organic and physical chemistry, later taking an interest in biological processes as well. In 1970 Lehn became Professor of Chemistry at the Université Louis Pasteur in Strasbourg and since 1979 he has been Professor at the Collège de France in Paris. The research work of Jean-Marie Lehn led in 1968 to the synthesis of cage-like molecules that form inclusion complexes, the cryptates, with various metal ions. With this began his research on the chemical basis of 'molecular recognition' (i.e. the way in which a receptor molecule recognizes and selectively binds a substrate), which also plays a fundamental role in biological processes. For these studies Lehn received the Nobel Prize for Chemistry in 1987. In the 1975-85 period he also conducted research on the photochemical splitting of water and artificial photosynthesis for which he received the Pius XI Gold Medal of the Pontifical Academy of Sciences in 1981. Over the years, Lehn's main line of research has expanded from the studies on molecular recognition to the definition and exploration of a new field of chemistry, which he proposed calling 'supramolecular chemistry' as it deals with the complex entities formed by the association of two or more chemical species held together by intermolecular forces, whereas molecular chemistry studies the features of the entities constructed from atoms linked by covalent bonds. His work has also covered supramolecular catalysis, artificial enzymes and transport processes. It has further extended to the design of functional molecular and supramolecular devices belonging to the areas of molecular electronics, ionics and photonics. More recently a main line of development has been the design of 'programmed' systems that undergo self-organization by the spontaneous assembly of suitable components into well-defined supramolecular architec tures following an Aufbau plan. The long-range goal is the study and design of organized matter and the progressive build-up of complexity. The results of the work of Jean-Marie Lehn have been described in more than 700 scientific publications.
