Strongly phosphorescent palladium(II) complexes of tetradentate ligands with mixed oxygen, carbon, and nitrogen donor atoms : photophysics, photochemistry, and applications

摘要

A healthy glow: A series of palladium(II) complexes with tetradentate O N C N ligands (see structure) exhibit intense green phosphorescence and long-lived excited states with emission quantum yields and lifetimes up to 22 % and 122-μs, respectively. The complexes show potential as novel functional materials, with promising results in a variety of applications, such as oxygen sensing, photocatalysis, and organic light-emitting diodes.
