Ir(MDQ)2(acac) Powder Description

Ir(MDQ)2(acac) has a 2-methyldibenzo[f,h]quinoxaline ligand that coordinates with the iridium metal center via the formation of Ir-N and Ir-C bonds.

Ir(MDQ)2(acac) is another family member of iridium complexes, which are the most effective phosphorescent emitters employed in OLEDs. Devices based on Ir(MDQ)2(acac) emit orange-red light, with a maximum emission of 600-614 nm. OLEDs with Ir(MDQ)2(acac) as an emitting layer material give great brightness and exceedingly-high external quantum, current, and power efficiencies.
