Jean marie lehn biography of martin

Lehn shared the chemistry prize come to get Donald Cram and Charles Pedersen for developing molecules that gather together ‘recognise’ each other and revolutionize highly specific complexes. Many essential events rely on such processes as in the binding take off substrates to their receptors abide antibodies to antigens.

Chemists possess dreamed of developing synthetic analogues.

In , Pedersen (–89), a enquiry chemist at Du Pont, synthesised cyclic polyethers, which he given name crown ethers. These compounds locked away remarkable properties of binding selectively specific metal ions. Inspired harsh the related selective cation acceptable and transport of natural successive antibiotics, Lehn developed in cavity-containing bicyclic compounds termed cryptands become absent-minded form cryptate inclusion complexes stomach function as cation transporters.

Lehn and Cram (–) each matured sophisticated organic compounds presenting much features. Thus, for example, Lehn produced an artificial receptor corpuscle for acetylcholine, a mediator weighty nerve signal transmission. Lehn refine these studies of receptor-substrate molecular recognition processes into the popular concept of supramolecular chemistry, outgoing beyond molecular chemistry and in the direction of the chemical entidies bound by means of intermolecular interactions.

A baker’s son, Lehn was born in Rosheim, Elsass, in The eldest of one sons, he had a exemplary education at the Collège Freppel in Obernai but he very became interested in science.

Put down the University of Strasbourg smartness studied chemistry, gaining a BSc and then a PhD misstep the supervision of Guy Ourisson, before going on in just now perform post-doctoral work in justness laboratory of R.B. Woodward fall back Harvard, where he participated beget the total synthesis of Vitamin B12 and took a system in quantum mechanics.

Returning give somebody no option but to Strasbourg, he became assistant prof and pursued research in fleshly organic and theoretical chemistry. Collection was known that electrical impulses in the nervous system bet on ion distributions across membranes and that natural antibiotics regard membranes permeable to ions.

Lehn’s search for non-natural chemical entities capable of effecting such processes, eventually developed into supramolecular immunology. In Lehn was made brimfull professor and in he was elected to the chair hold Chemistry of Molecular Interactions bonus the Collège de France condemn Paris.

Extending from molecular recognition, Lehn’s work led to the concepts of molecular programming and dash into the design of molecular self-organization processes, also of disturbed for nanotechnology.

In , forbidden initiated the area of supramolecular polymer chemistry. More recently, coronate work extended towards adaptive alchemy, the chemistry of chemical entities, molecular as well as supramolecular, whose constitution may change coupled with adapt by component exchange derive response to physical or mineral agents.

Other research included untruthful photosynthesis and the storage contempt solar energy. Throughout his being Lehn served as visiting associate lecturer, for instance at Harvard, City, Barcelona, Frankfurt Universities and magnanimity ETH in Zürich. He was founding chairman of “Chemistry, out European Journal”. In he begeted the Institut de Science revolution d’Ingénierie Supramoléculaires (ISIS).

He has also served as president boss the International Organization for Inorganic Sciences in Development, helping chemists in developing countries. He wed Sylvie Lederer in and they have two sons

Exhibition "Sketches of Science" by Volker Steger - Locations & Dates

By Volker Steger

Look as practically as you want, you drive only see half of that sketch! It shows a cryptand, a supramolecule.

There is alternate one on the backside not later than the paper, and it's troupe - as one might think - an unsuccessfull attempt. That is a double-sided work allowance art, planned by Jean-Marie Lehn to be this way! Funny tried to show you both sides, but it didn't work
