Jean-Marie Lehn is a famous French chemist. He received the Nobel Prize in Chemistry together with Donald Cram and Charles Pedersen in 1987 "for their development and use of molecules with structure-specific interactions of high selectivity
Professor Lehn's main research area is supramolecular chemistry, especially the synthesis of point ether. Lehn expanded on Pedersen’s achievement in creating crown ethers, a class of two-dimensional, ring-shaped organic compounds that are capable of selectively recognizing and combining with other molecules. In the course of his efforts to synthesize three-dimensional molecules that would possess similar reactive characteristics, Lehn created a molecule that combines with the chemical acetylcholine, which is an important neurotransmitter in the brain. His work raised the possibility of creating totally artificial enzymes that would have characteristics superior to their natural counterparts in the human body.
