and tris(quinolin‐8‐yloxy)aluminum as an emitter are made either by vacuum deposition or by solution processing, and show much higher maximum efficiencies than the commonly used N,N′‐di(naphthalen‐1‐yl)‐N,N′‐diphenylbiphenyl‐4,4′‐diamine device (3.6 cd A−1) of 7.0 cd A−1 and 6.9 cd A−1, respectively. In addition, the solution processed blue phosphorescent OLEDs employing the synthesized materials as hosts
