Abstract

A novel Re complex functionalized by a hole-transport and an electron-transport groups was utilized to fabricate organic light-emitting devices (OLEDs). A current efficiency up to 8.2 cd A-1 corresponding to a power efficiency of 4.6 ml W-1 and a peak brightness as high as 5500 cd m-2 were obtained. These results represent the best values reported for OLEDs based on rhenium complexes. Short lifetime, enhanced carrier injection capability of Re complex, and efficient charge-trapping followed by exciton confinement in the emissive layer should be responsible for the outstanding electrophosphorescent performances. © 2006 Elsevier B.V.
