The photo- and electroluminescence properties of a series of novel, heteroleptic, mer-cyclometallated iridiumcomplexes have been fine-tuned from green to blue by changing the substituents on the pyridyl ring of the phenylpyridyl ligand. The X-ray crystal structures of two Ir-based triazolyl complexes are reported.
