Abstract
Described herein are transition metal complexes containing nickel(II), as the central metal atom, and tridentate and tetradentate ligands. The transition metal complexes also include an ancillary ligand with strong σ-donating properties. The ancillary ligand enhances the luminescence by increasing the chances of populating the emissive state. The transition metal complexes are emissive at room temperature and/or low temperature in various media, rendering them useful as light-emitting materials for OLEDs.
