Supramolecular Chemistry Molecular Hosts and Their Guests 

He achieved levels up to 90 percent ee (ee = enantiomeric excess, i.e., 90 percent ee equates to 95 percent D + 5 percent L in one chamber and 95 percent L + 5 percent D in the other). The achievements of Charles J. Pedersen, Jean-Marie Lehn, and Donald J. Cram were recognized by their receipt of the 1987 Nobel Prize in chemistry. In 1991, Cram s group synthesized the incredibly reactive cyclobutadiene molecule (see the previous section) in the center of an inert host. The complex is stable at room temperature for indefinite periods.
