Synthetic Route of 52409-22-0, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 52409-22-0, Pd2(DBA)3, introducing its new discovery.
The novel electron-transporting moiety of 2,7-diazacarbazole was used to construct a bipolar host molecule for phosphorescent organic light-emitting diodes (PHOLEDs). This moiety was incorporated with typical hole-transporting carbazole moieties to synthesize a 2,7-diazacarbazole/carbazole hybrid called 9-(3,5-bis(carbazol-9-yl)phenyl)?2,7-diazacarbazole. The hybrid exhibits a high triplet energy above 2.88 eV and very high glass transition temperature of Tg = 148C. It shows good thermal stability owing to the rigid nature of its symmetrical bipolar structure. The 2,7-diazacarbazole-based host material turns on at 3.6 and 3.7 V and approaches external quantum efficiencies above 16.0 and 22.6% in blue and green PHOLEDs, respectively. These results demonstrate that 2,7-diazacarbazole should be an excellent electron-transporting unit for bipolar phosphorescent hosts.
