Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Bis[2-(1-isoquinolinyl-N)phenyl-C](2,4-pentanedionato-O2,O4)iridium(III), is researched, Molecular C35H27N2O2Ir, CAS is 435294-03-4, about Imidazolyl-Phenylcarbazole-Based Host Materials and Their Use for Co-host Designs in Phosphorescent OLEDs.Formula: C35H27N2O2Ir.
In recent years, owing to the demand for high-efficiency phosphorescent organic light-emitting devices (PhOLEDs), many studies were conducted on the development of bipolar host materials. Imidazolyl-phenylcarbazole-based host materials, i. e., i.m.-CzP, i.m.-CzPCz, i.m.-CzPCMe3, and i.m.-OCzP, were synthesized to obtain high-efficiency green and red-emitting PhOLEDs. With i.m.-OCzP as the host, satisfactory peak efficiencies of 22.2 (77.0 cd A-1 and 93.1 lm W-1) and 14.1% (9.0 cd A-1 and 10.1 lm W-1) could be obtained, resp. To further improve the performance of the devices, an electron transport material, bis-4,6-(3,5-di-3-pyridylphenyl)-2-methylpyrimidine (B3PyMPM) was selected to construct a co-hosted system. The efficiency of i.m.-OCzP combined with B3PyMPM forming co-hosts could also achieve high values of 23.0 (80.0 cd A-1 and 98.8 lm W-1) and 16.5% (10.2 cd A-1 and 13.4 lm W-1) for green and red PhOLEDs, resp. These results exhibited that the proposed bipolar hosts have great flexibility in adjusting the carrier balance of EML in OLEDs, demonstrating their ingenious design and high potential.
