Born 30 Sep 1939.French chemist who shared (with Charles J. Pedersen and Donald J. Cram) the 1987 Nobel Prize for Chemistry, for his contribution to the laboratory synthesis of molecules that mimic the vital chemical functions of molecules in living organisms. Such molecules have a highly selective, structure specific interaction. These molecules can “recognize”each other and choose with which other molecules they will form complexes. Of low molecular weight and with very special properties, the molecules in these compounds bind in a selective manner, like a key fits a lock.
