The MacDonnell lab is interested in developing new molecular catalysts and materials with interesting optical, photochemical, electrochemical, stereochemical and bioactive properties. In particular, we have been heavily involved in the synthesis and characterization of new ruthenium-polypyridyl complexes containing unusual redox and photoactive ligands. The complexes exhibit a wide range of behaviors that makes them potential useful in areas as diverse as solar-energy harvesting, chiral separations and photocatalysis. In order to study these complexes we rely on a broad range of spectroscopic and spectrometric techniques including: electrochemistry, spectroelectrochemistry, photochemistry, crystallography, electron paramagnetic resonance, NMR and magnetic susceptibility.
