Synthesis of luminescent and electrochemiluminescent coordination compounds

We are working on the synthesis of luminescent coordination complexes of metals including gold, ruthenium and iridium and the lanthanides for use as biological imaging agents and for sensor development. A number of ligand systems are under investigation and we have a particular focus on N-heterocyclic carbenes (NHCs). Previously we reported the first examples of electrochemiluminescent Ru(II) and Ir(III) complexes of NHC ligands and more recently we described a novel stepwise synthetic methodology for the preparation of heterobimetallic Group 11 and 12 complexes of symmetric ‘pincer type’ NHC ligands.
