Finely-tuned blue-phosphorescent iridium complexes based on 2-phenylpyridine derivatives and application to polymer organic light-emitting device
We have developed new blue-phosphorescent iridium complexes based on 2-phenylpyridine derivatives with pertinent substituents and an ancillary ligand to accomplish selective tuning of the HOMO and LUMO levels toward high energy gap: A polymer light-emitting device doped with the blue phosphor was fabricated to show blue emission.
