Nucleophilic substitution of fluorine atoms in 2,6-difluoro-3-(pyridin-2- yl)benzonitrile leading to soluble blue-emitting cyclometalated Ir(III) complexes

摘要

New functionalized phenylpyridine ligands and their derived heteroleptic cyclometalated Ir(III) complexes have been synthesized. The complexes possess a combination of important properties: (i) blue emission, (ii) good photoluminescence quantum yields, and (iii) good solubility in organic solvents, making them very attractive as phosphorescent dopant emitters for solution-processable light-emitting devices.
