Interlocked molecules: Mix and match
Abstract
Catenanes — molecules comprising interlocked rings not covalently bonded to each other — initially attracted attention for their unusual structures, but are now being used in molecular electronic devices. Their synthesis, which has traditionally required pre-organization of the precursors via non-covalent interactions, has often been achieved by interlocking a ring containing |[pi]|-donor groups with one containing |[pi]|-acceptor groups.
