Red and green phosphorescent metal complexes in OLEDs have shown performances that meet the practical industrial applications in terms of device efficiency and stability, whereas the applications of blue phosphorescent metal complexes have been hampered by their unsatisfactory stability. High energy of the excited states and thermal population of d-d states are conceived to cause the decomposition of blue light-emitting complexes. The development of d⁸ blue phosphorescent transition metal complexes by using tetradentate ligand is expected to enhance the emission efficiency and stability simultaneously. Progress in blue light-emitting platinum(Ⅱ) and palladium(Ⅱ) complexes and their performances in OLEDs is reviewed. By shedding light on the ligand structures-photophysical and stability relationships, we try to provide suggestions to the future effort for developing blue light-emitting metal complexes.
