“…The straightforward manner in which these properties can be tuned has positioned these types of compounds at the forefront of modern photochemistry. Although salts can be also employed for OLED applications, in addition to the light-emitting electrochemical cell (LEC) technology, neutral compounds are usually used as a emitter for device fabrication . As a consequence, the neutral iridium(III) complexes have awakened more interest than the iridium salts.…”

“…Phosphorescent cyclometalated Ir(III) complexes have attracted extensive interest due to their broad range of emission colours and high phosphorescence quantum efficiencies [9,10]. These unique properties are quintessential for a complex to be explored as a promising candidate in the applications of organic light-emitting diodes (OLEDs) [11,12] and light-emitting electrochemical cells (LEECs) [13,14].…”

Molecular phosphorescent heteroleptic bis-tridentate iridium(III) emitters have been prepared via η -arene intermediates. In the presence of 4.0 mol of AgOTf, the complex [(IrCl{κ -N,C,N-(pyC HMe py)})(μ-Cl)] (1; pyC H Me py=1,3-di(2-pyridyl)-4,6-dimethylbenzene) reacted with 9-(6-phenylpyridin-2-yl)-9H-carbazole (PhpyCzH) and 2-phenoxy-6-phenylpyridine (PhpyOPh) to give [Ir{κ -N,C,N-(pyC HMe py)}{κ -C,N,C'-(C H pyCzH)}]OTf (2) and [Ir{κ -N,C,N-(pyC HMe py)}{κ -C,N,C'-(C H pyOPh)}]OTf (3). The X-ray diffraction structures of 2 and 3 reveal that the carbazolyl and phenoxy substituents of the C,N,C' ligand coordinate to the metal center to form an η -arene π bond. Treatment of 2 and 3 with KOtBu led to the deprotonation of the coordinated carbon atom of the η -arene group to afford the molecular phosphorescent [5t+4t'] heteroleptic iridium(III) complexes [Ir{κ -N,C,N-(pyC HMe py)}{κ -C,N,C'-(C H pyCz)}] (4) and [Ir{κ -N,C,N-(pyC HMe py)}{κ -C,N,C'-(C H pyOC H )}] (5). These complexes are green emitters that display short lifetimes and high quantum yields of 0.73 (4) and 0.87 (5) in the solid state.
