Cyclometalated platinum complexes have been the focus of considerable research, driven in large part by their potential use as sensitizers, photocatalysts, and chemosensors. Platinum complexes have also attracted strong interest as luminescent materials for use in organic light emitting diode (OLED) based display and lighting applications due to their ability to harvest both electro-generated singlet and triplet excitons, resulting in a theoretical 100% electron-to-photon conversion efficiency. Despite the dominance of iridium at present, platinum remains an exciting field of study. If the intrinsic electroluminescent properties of phosphorescent platinum complexes can be unmasked and optimized, these complexes can provide a viable alternative to existing iridium emitters and spur further growth in this emerging field. Planar platinum complexes possess excellent structural flexibility, with the ability to employ various cyclometalating ligands. New platinum complexes were synthesized and characterized. These Platinum complexes are highly luminescent, emitting blue to green light in solution. Finally, developed Pt-complexes were tested as dopants in prototype phosphorescent organic light-emitting diode devices and found to show deep blue electroluminescence with high emission efficiency and color purity.
