N2 - A cyclo-meta-phenylene (CMP) macrocycle with donor/acceptor substituents was designed. After optimization of the synthesis routes, the CMP congener was synthesized via [3 + 3] assembly of phenylene panels in moderate yield. The molecule showed a highly crystalline nature, and a single crystal formed upon sublimation. The molecule was transparent in the visible light region and was thermally robust with a decomposition temperature of 583◦C. The effect of the donor/acceptor substituents was evaluated for charge carrier transport layers in emitter-doped phosphorescent OLEDs, which showed a dramatic improvement in its electron transporting ability as well as power efficiency in devices.
