Macrocycles, and related acyclic polydentate ligand strands, provide a lot of control over the environment of the transition metal ions they encapsulate and this can be exploited in efforts to prepare complexes with interesting structural, electrochemical, magnetic and/or luminescent properties. Such properties provide the complex with functionality which, with further development, may ultimately lead to potential applications, for example as nano-switches or memory devices.

We have developed a range of macrocyclic and polydentate ligands that contain within their frameworks groups capable of bridging the incorporated metal ions. This lecture will introduce and report on the development of self-assembling systems which feature heterocycle-bridging of the transition metal ions, with particular focus given to (a) systems with interesting magnetic properties and (b) systems which illustrate control of molecular architecture by choice/control of pH, stoichiometry, ligand isomer, 'arm-length' and steric/electronic factors.
