Uses
Used in Green Phosphorescent OLED Devices:
Acetylacetonatobis(2-phenylpyridine)iridium is used as a dopant/emitter in green phosphorescent OLED devices for its high brightness and quantum efficiency. It has achieved a brightness of 130,800 cd/m2 at a current density of 15.5 mA/cm2 (13 V) and a high quantum efficiency of 15-16%.
Used in OLED Materials Research:
Acetylacetonatobis(2-phenylpyridine)iridium is used as a key material in the research and development of OLED devices due to its high quantum yields and efficient energy transfer properties. When doped into 3,5-Diphenyl-4-(1-naphthyl)-1H-1,2,4-triazole (TAZ), it has demonstrated very high external quantum efficiencies of 19.06 ± 1.0% and luminous power efficiencies of 60 ± 5 lm/W. These impressive results are attributed to the nearly 100% internal phosphorescence efficiency of Ir(ppy)2(acac), balanced hole and electron injection, and triplet exciton confinement within the light-emitting layer.
Used in Enhancing OLED Device Performance:
Acetylacetonatobis(2-phenylpyridine)iridium has shown higher external quantum efficiency compared to other similar materials, such as Ir(ppy)3. This is suggested to be due to the preferential alignment of Ir(ppy)2(acac) molecules, with their transition dipole moment parallel to the substrate, whereas the orientation of Ir(ppy)3 molecules is nearly isotropic. This property makes Ir(ppy)2(acac) a valuable component in the design and optimization of OLED devices for improved performance and efficiency.
Check Digit Verification of cas no
The CAS Registry Mumber 337526-85-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,7,5,2 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 337526-85:
(8*3)+(7*3)+(6*7)+(5*5)+(4*2)+(3*6)+(2*8)+(1*5)=159
159 % 10 = 9
So 337526-85-9 is a valid CAS Registry Number.

The transmetalation reaction of a chiral-bidentate NHC-silver complex to racemic [Ir(μ-Cl)(ppy)2]2 operates with kinetic resolution leading to chiral octahedral NHC-iridium(iii) complexes and enantio-enriched bis-cyclometalated iridium(iii) complexes. The iridium(iii) complexes demonstrated efficient catalytic activities in intermolecular [2+2] photocycloaddition reactions and in asymmetric Friedel-Crafts alkylations, respectively.
