Tris(1-phenylisoquinoline)iridium(III), Ir(piq)3 is a deep red phosphorescent dopant material.
Due to their high electron affinities, quinoline/isoquinoline-based compounds have received considerable attention in optoelectronic materials. With greater π-electronic conjugation in the isoquinoline ring, the energy of the lowest unoccupied molecular orbital (LUMO) is significantly lowered, and the energy gap is reduced.
Ir(piq)3, together with Ir(piq)2acac, are the ones that have been most studied in theisoquinoline iridium complex family. The 'piq' unit of the ligand part can partially suppress the triplet-triplet annihilation and show short phosphorescent lifetimes.
