Abstract

In the deep red: A biscyclometalated deep-red phosphorescent dopant containing a new ancillary ligand, iridium(III) bis(1-phenylisoquinolinato-N, C2′) (2-(benzo[d]oxazol-2-yl)phenol) (Ir(piq)2bop) has been designed and synthesized. By doping the new complex into Bebq 2 (Bebq2=bis(10-hydroxybenzo[h] quinolinato)beryllium), a saturated red-emitting PHOLED device was obtained. At a luminescence of 100 cd m-2, the device shows efficiencies of 10.3 cd A-1 and 9.1 Lm W-1 with CIE coordinates of (0.67, 0.33). Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
