摘要

Microwave synthesis of tris-ortho-metalated Ir(Ⅲ) complexes was performed and resulted complexes were applied to the electrophosphorescent devices. For synthesis of Ir(ppy)_3, the product was obtained by 30 min. microwave irradiation. That is microwave irradiation reduced the reaction time to 1/20 of that under conventional heating. Furthermore, we succeeded the rapid microwave synthesis of tris(2-phenyl-1-quinoline)iridium(Ⅲ), Ir(phq)_3, which is hard to synthesis by conventional method. An electrophosphorescent device with Ir(phq)_3 as a dopant in emitting layer was developed. It demonstrated a high-efficient orange emission with maximum luminous efficiency of 33.4 cd/A and a power efficiency of 11.7 lm/W at 800 cd/m~2. The color of emission corresponds to CIE coordinates x = 0.56, y = 0.43. The device showed a projected operational lifetime, namely T_(1/2), of 6500 h at an initial brightness of 1500cd/m~2 under constant dc drive.
