Iridium complexes can be used as high efficient light-emitting materials in OLED devices according to its triplet light-emitting properties. In present work, we report two series of iridium complexes with green and red light emitted, respectively. Ir(ppy)<sub>2</sub>Ac, Ir(ppy)<sub>2</sub>Vb, Ir(btp)<sub>2</sub>Ac, and Ir(btp)<sub>2</sub>Vb can be used as good phosphorescent light-emitting materials for EL devices. Particularly, these iridium complexes give a possibility to form unique polymer material acting at least as the same as host-guest light-emitting system, which is rather complicated in fabricating process. By the improvement of injecting balance of hole and electron in the device, these iridium complexes can be considered as the potential high efficiency material for OLED use.
