Ir(dpm)(piq)2, namely bis(phenylisoquinoline)(2,2,6,6-tetramethylheptane-3,5-dionate) iridium(III), is an iso-structure to Ir(dpm)PQ2. Ir(dpm)(piq)2 has one 2,2,6,6-tetramethylheptane-3,5-dionate with two bulky tert-butyl groups and two phenylisoquinoline ligands coordinated to the iridium core.
Ir(dpm)(piq)2 is a deep red emitting phosphorescent dopant and relatively about 30 nm red-shifted while comparing that of Ir(dpm)PQ2.
