Usage

Classification

Iridium complex, Phosphorescent blue emitter, Organic light-emitting diodes, Organic electronics.

Applications

Bis[2-(4,6-difluorophenyl)pyridinato-C2,N](picolinato)iridium, abbreviated as FIrPic, F2IrPic or Ir(difppy)2(pic), is one of the most investigated bis-cyclometallated iridium complexes in particular in the context of organic light emitting diodes (OLEDs). This is because of its attractive sky-blue emission, high emission efficiency, and suitable energy levels as a phosphorescent dopant material.

Molecular-engineered [Ir(Fppy)2(Mepic)] towards efficient blue-emission

A novel Ir(III) complex, [Ir(Fppy)2(Mepic)] (Fppy = 2-(2,4-difluorophenyl)pyridinate; Mepic = 3-methylpyridine-2-carboxylate) was engineered to show a blue phosphorescence with an impressive unitary quantum yield in our search for luminescent metal complexes for low cost displays and efficient lighting devices. Application of the Golden rule through Franck-Condon spectral analyses along with TD-DFT calculations and comparisons to the [Ir(Fppy)2(pic)] complex have provided insights on the mixing extension between charge-transfer (CT) and ligand-centered (LC) excited states in the emissive lowest-energy triplet transition for different media. The relatively narrow and vibronically-structured emission of [Ir(Fppy)2(Mepic)] at 298 K mainly arises from a spin-orbit-induced mixed 3MLCT-LCIr(Fppy)→Fppy/3LLCTFppy→Mepic excited state, with an enhanced MLCT character because of the methyl addition to pic. In frozen media at 77 K, the CT contribution is extinguished, leading to a pure LCFppy emission, with a similar emissive spectral profile to the free ligand, FppyH. The efficient blue emission shows that the complex is suitable for high-performance light-emitting devices and for thermo- and rigidity-sensors.

Inter-ligand energy transfer and related emission change in the cyclometalated heteroleptic iridium complex: Facile and efficient color tuning over the whole visible range by the ancillary ligand structure

We report a novel color tuning methodology in the electrophosphorescent iridium complex by substituting one cyclometalating ligand to an ancillary ligand as an emitting center. Highly efficient exothermic inter-ligand energy transfer (ILET) from the MLCT

Synthetic method of organometallic iridium compound

A synthetic method for preparing organometallic iridium compounds is provided and includes the two steps of (1) synthesizing a di-iridium compound with a halogenated bridge: L2Ir(μ?X)2IrL2, L; and (2) reacting L2Ir(μ?X)2IrL2 with a ligand to give the product [C?]N]2Ir (LX). The invention is an improvement over the traditional method for preparing such compounds and has the advantages of shortened reaction time, increased yield, and products of over 99% purity obtained without chromatography.
