Cao, Hong-Tao published the artcileModification of iridium(III) complexes for fabrication of high-performance non-doped organic light-emitting diode, COA of Formula: C19H14N2, the publication is Dyes and Pigments (2015), 8-16, database is CAplus.
Four novel Ir(III) complexes containing 1,2-diphenyl-1H-benzoimidazole as cyclometalated ligands were synthesized and characterized. The complexes displayed strong emissions around 492 nm with high luminescence quantum yields of 70-92% in CH2Cl2 solution at 298 K. Doped OLEDs based on the complexes were prepared, which showed a peak current efficiency of 34.5 cd A-1, power efficiency of 40.1 lm W-1. Nondoped OLEDs using the complexes as emitters were then fabricated for further study of their electroluminescence properties. One nondoped device possessed outstanding performance with a maximum current efficiency of 19.8 cd A-1 and power efficiency of 20.4 lm W-1 while simultaneously displaying low efficiency roll-off at high luminance.
