Usage

Uses

Used in Organic Light Emitting Diodes (OLEDs):
Firpic is used as a phosphorescent dopant material for its attractive sky-blue emission, high emission efficiency, and suitable energy levels. It is typically doped into host matrices such as tetra-aryl silanes and short conjugation length carbazole derivatives, showing a good quantum efficiency.
Used in Suzuki Reaction:
Firpic is also utilized in the Suzuki reaction, a widely used method in organic chemistry for the formation of carbon-carbon bonds, particularly in the synthesis of various organic compounds and materials.

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.

Highly efficient phosphorescence from cyclometallated iridium(III) compounds: Improved syntheses of picolinate complexes and quantum chemical studies of their electronic structures

We report a new method to make heteroleptic cyclometallated iridium(III) complexes that employs 1,2-dimethoxyethane (DME) instead of the commonly used 2-ethoxyethanol for the addition of ancillary ligands to chloro-bridged dimeric iridium species. Thus, p

According to one embodiment, a method of synthesizing an organometallic iridium monomer compound includes obtaining a dimeric iridium compound having a halogenated bridge, refluxing a mixture comprising the dimeric iridium compound, a base, an ancillary ligand, and 1,2-dimethoxyethane for forming a precipitate of an organometallic iridium monomer, and filtering the refluxed mixture to collect the organometallic iridium monomer precipitate.

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).

PRODUCTION OF IRIDIUM COMPLEXES

The invention relates to a process for producing a trivalent hexadentate ortho-metallated iridium complex with an iridium compound and a coordination compound as starting materials, which is characterized in that a monovalent iridium dinulear complex represented by the following formula (I)is used:(wherein A represents a non-conjugated diene compound; and X represents a halogen atom).According to the invention, it is possible to carry out the successive reactions in the same reaction vessel (i.e., one-pot reaction) by using the complex produced in the above process in the next step without isolation and purification.
