Imidazo[1,2-b]pyridazine as Building Blocks for Host Materials for High-Performance Red-Phosphorescent Organic Light-Emitting Devices
A novel electron-transporting unit, imidazo [1,2-b]pyridazine (IP), was first reported for developing host materials. The IP moiety possesses excellent electron-transporting ability and great thermal stability. Using carbazole as p-type units and IP as n-type units, several bipolar host materials, namely, IP6Cz, IP68Cz, IP36Cz, and IP368Cz, were developed through altering the substitution site of the IP core. Among these four materials, 6-site-substituted IP6Cz and 6,8-site-substituted IP68Cz exhibit the best electroluminescence (EL) performance. IP6Cz- and IP68Cz-based red phosphorescent organic light-emitting diodes using Ir(pq)(2)acac as the emitter exhibit extremely high EL efficiency with the maximum external quantum efficiency (eta(ext,max)) of 26.9 and 25.2% and an insignificant efficiency roll-off. Moreover, IP6Cz- and IP68Cz-based deep-red devices doped by Ir(piq)(2)acac also show satisfactory EL performance with a eta(ext,max) of 20.5 and 19.9%, respectively. The influence of different substitution sites of the IP core on the photophysical and electrochemical properties was systematically investigated. This study demonstrates that IP could be a first-rate electron-transporting unit for bipolar materials for red-emitting devices.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 88-17-5. Formula: C7H6F3N.
