Synthesis, structure and efficient electroluminescence of a heteroleptic dipyridylamido/bis(pyridylphenyl)iridium(iii) complex†
Abstract
A neutral 2,2′-dipyridylamido (dpa)-supported bis(cyclometalated) iridium(III) complex [Ir(ppy)2(dpa)] (ppy = o-(2-pyridyl)phenyl) has been synthesized and structurally characterized for the first time, which emits green electroluminescence with high current efficiency (123.5 cd A−1) and high power efficiency (43.2 lm W−1).
