High-purity (>99.0%) and available online for priority dispatch, Bis(2-phenylquinoline)(2,2,6,6-tetramethylheptane-3,5-dionate)iridium(III), CAS No. 713079-03-9, Sublimed ≥99.0%

Bis(2-phenylquinoline)(2,2,6,6-tetramethylheptane-3,5-dionate)iridium(III) - Ir(dpm)PQ2, also known as Ir(PQ)2(tmd) is an orange to red phosphorescent emitter. The ligand 2,2,6,6-tetramethylheptane-3,5-dionate coordinated to the iridium centre is sterically hindered with two bulky tert-butyl groups at both ends.

Ir(dpm)PQ2 is often either used in pure red as a single emitting layer material or in white emitting highly efficient OLED devices for its low lying triplet energy state and greater stability, preventing triplet-triplet annihilation thus leading to higher device efficiencies.
