Chemistry: Molecular socks in a drawer

Michael D. Ward1

Top

Dynamic combinatorial chemistry is a deft way to identify the most stable forms in a complex mixture of interconverting compounds. Even more cunningly, it can also be used to sort related molecules by crystallization.

As chemists seek to produce increasingly complex molecules and molecular assemblies, it has become evident that complexity often comes at a price — the many different reaction pathways can generate unwanted mixtures and side products. This is particularly true when the reaction pathways and products are similar energetically.
