A new iridium(III) complex with efficient photo- and electro-luminescent properties
摘要:
A new complex of Ir(pi)(2)(acac) (L = 2-(4-bromophenyl)-1-ethyl-1H-phenanthro[9,10-d]imidazole) was designed and synthesized. Its molecular structure was determined by a single-crystal X-ray diffraction analysis. The Ir(III) complex showed characteristic phosphorescence with an emission of 570 nm and a high quantum efficiency of 28%. A high performance yellow OLEDs was successfully fabricated by using this Ir(III) complex as dopant. (C) 2011 Elsevier B.V. All rights reserved.
