Using Quinoxaline as template combined Triarylamines applied for the research of the organic light emitting diodes. Because of the characteristic of bi-functional and dipolar, they made that the materials could form exciton effectively. By taking advantage of the good electron affinitive property of quinoxlines and the efficient hole-injection/transporting property of triarylamines, we thought to hybridize them into a fused, tri-cyclic aromatic framework with a central 7-membered core (QLIMS). In addition, we thought to examine if the unique of mode of connection is influential to the structural, optical, morphological, redox, and optoelectronic profiles of the resulting materials.
In marked contrast to common donor-acceptor based materials, this new type of bipolar compounds are dual functional and display unique optical, morphological, redox and optoelectronic propensities. In conjunction with a suitable electron-transporting material- Alq3, the type-I QLIMS serve as potential green electron-emitters in light-emitting devices. Remarkably, the Q-An also acts as a good hole-emitter, reaching a maximum EL intensity of 12347 cd/m2.The polymer doped PVK and combined a electron-transporting material-PBD can light by energy transferred. It showed good luminescent efficiency.
