New copper complex offers easy access to complex structures

Chemists working at the University of Cambridge in the UK have discovered a new dicopper complex capable of forming diverse supramolecular structures.

The creation of supramolecular structures for a wide variety of uses has been something that chemists have pursued for years and, as such, new methods to access these structures are constantly sought.  Jonathan Nitschke and colleagues are prominent figures in this field and have just reported a new copper complex that self assembles into larger architectures.

The team first assembled the copper complex and then showed they could modified it at two points. This is done either by substitution of solvent molecules with ligands capable of linking multiple complexes or by modifying the imine bonds. Using both these approaches and varying the ligands, it was possible to achieve the templated synthesis of 26- and 52-membered macrocycles. More complex assemblies that utilise this approach are currently being investigated.
