•Yellowish green triplet emitter derived from phenylbenzothienopyridine ligand.•High quantum efficiency yellowish green phosphorescent organic light emitting diodes.•High quantum efficiency of 22.4% at 1000 cd/m2 with a color coordinate of (0.43, 0.57).
A yellowish green phosphorescent dopant derived from phenylbenzothienopyridine ligand, iridium (III) [bis(1-phenylbenzo[4,5]thieno[2,3-c]pyridinato-N,C2]picolinate. (Ir(DTNP)2pic) was synthesized and the device performances of the Ir(DTNP)2pic was studied. The Ir(DTNP)2pic dopant exhibited yellowish green emission at 548 nm and showed a high quantum efficiency of 22.4% at 1000 cd/m2 with a color coordinate of (0.43, 0.57) in yellowish green phosphorescent organic light-emitting diodes.
