The hole story of how cage molecules could transform synthesis and separation
It is these extreme confinement effects that ‘enables us to do chemistry that we can’t do in traditional ways’, says Angela Grommet from the Weizmann Institute of Science in Israel who recently wrote a review 2 on the topic. After 35 years of research, chemists are now starting to unlock the potential of confinement by designing molecular cages that fold up long molecules into huge macrocycles, or creating cavities that can separate deuterium from hydrogen. In the future, confined spaces could rival enzymes in their ability to catalyse reactions or protect unstable species, turning them...
