摘要：

A new iridium complex was synthesized and demonstrated a saturated red light emission in organic light-emitting diodes (OLEDs). The maximum brightness of 2800 cd/m(2) and the external quantum efficiency of 5.5% were achieved in multilayer OLEDs. The peak wavelength of the emission was found to be at 677 nm with the Commission Internationale de l'Eclairage (CIE) coordinates of (0.71, 0.27). (C) 2005 Elsevier B.V. All rights reserved.
