Bis-cyclometalated iridium complexes are well-known for their efficient triplet-state luminescence and excited-state redox chemistry. The Teets group has advanced the idea that the ancillary ligand(s) in these compounds can substantially alter the redox and photophysical properties, and this lecture highlights some work in this area. Postsynthetic modification strategies give rise to new structure types and have led to the discovery of efficient visible-light phosphors. Other ligand-design strategies produce compounds with efficient red or near-infrared phosphorescence, as well as a class of potent photoreductants which outperform state-of-the-art photosensitizers in photoinduced electron-transfer reactions.
