Jean-Marie Lehn

Born the September 30th 1939 with Rosheim in Alsace, Jean-Marie Lehn is a Chimiste French, Nobel Prize of chemistry in 1987, specialist in the Chimie supramoléculaire.

Biography

After a beginning of career with CNRS (1960-66), it joined the Université Louis-Pasteur of Strasbourg, where it becomes professor in 1970. It is, since 1979, professor with the Collège de France with Paris. In 1968, its research led to the realization of Molécule S in the shape of cages comprising a cavity in which can be inserted another chemical species of adapted size and form, as a key fits in a lock. Thus its work began on the chemical basis from the " recognition moléculaire" (i.e. the property that a molecule has being used as receiver to recognize and retain a substrate), which also plays a big role in the biological processes . These studies were worth to him the Nobel Prize of chemistry in 1987 with American Donald J. Cram and Charles J. Pedersen, as well as a great number of distinctions and rewards national and international: Gold medal of CNRS in 1981 and Davy Medal of the Royal Society in 1997.

Work of Jean-Marie Lehn led gradually to the definition of a new field of the chemistry, which he proposed to call Chimie supramoléculaire because it is interested in the complex entities formed by the association of two or several chemical species dependant between them by intermolecular forces, whereas molecular chemistry studies the properties of the entries built starting from atoms bound by covalent forces. Starting from the molecular recognition, its research widened by including the catalysis and the processes of transport supra molecular. They also extended to the design from molecular components like bases from the electronic and the Photonique molecular. Another axis of development relates to the design of systems " programmés" capable of car-organization by spontaneous assembly of adequate components in architectures supra molecular given good.

In September 2006, it was named member of the High council of science and technology ().

Humanistic, it in particular signed, with other prizes winner of the Nobel Prize, a call asking that a delegation of the Committee of the Rights of the Child of UNO returns visit to a child Tibetan under house arrest since 1995 in China, Gendhun Choekyi Nyima, recognized like 11th Panchen LAMA by the 14th Dalaï Lama, Tenzin Gyatso.
