We have examined the theoretical implications of combining two main and three auxiliary ligands to form several Ir(Ⅲ) complexes featuring a transition metal as their core atom to identify some appropriate organic light-emitting diode (OLED) materials. By utilizing electronic structure, frontier molecular orbitals, minimum single-line absorption, triplet excited states, and emission spectral data derived from the density functional theory, the usefulness of these Ir(Ⅲ) complexes, including (piq)₂Ir(acac), (piq)₂Ir(tmd), (piq)₂Ir(tpip), (fpiq)₂Ir(acac), (fpiq)₂Ir(tmd), and (fpiq)₂Ir(tpip), in OLEDs was examined, where piq=1-phenylisoquinoline, fpiq=1-(4-fluorophenyl) isoquinoline, acac=(3Z)-4-hydroxypent-3-en-2-one, tmd=(4Z)-5-hydroxy-2, 2, 6, 6-tetramethylhept-4-en-3-one, and tpip=tetraphenylimido-diphosphonate. These complexes all have low-efficiency roll-off properties, especially (fpiq)₂Ir(tpip). Some researchers have successfully synthesized complexes extremely similar to (piq)₂Ir(acac) through the Suzuki-Miyaura coupling reaction.
