Application
Tris[1-phenylisoquinoline-C2,N]iridium(III), purified by sublimation, serves as a deep red phosphorescent dopant material with significant utility in optoelectronic applications. This compound, Ir(piq)3, is renowned for its high electron affinity, attributed to the enhanced π-electronic conjugation in its isoquinoline ring. This structure results in a reduced energy gap by significantly lowering the energy of the lowest unoccupied molecular orbital (LUMO). In its family of isoquinoline iridium complexes, Ir(piq)3 is frequently studied alongside Ir(piq)2acac because its 'piq' ligand unit effectively suppresses triplet-triplet annihilation, leading to shorter phosphorescent lifetimes.
