CAS 387859-70-3 | Tris[2-(4,6-difluorophenyl)pyridinato-C2,N]iridium(III)

Tris[2-(4,6-difluorophenyl)pyridinato-C2,N]iridium(III), commonly referred to as Ir(dfppy)₃, is an iridium(III) complex that is widely used in organic optoelectronic materials, especially organic light-emitting diodes. This compound has attracted great attention due to its excellent luminescence properties and stability.

Properties：

1. The compound is formed by a central iridium (III) ion (Ir³⁺) coordinated with three 2-(4,6-difluorophenyl)pyridine (dfppy) ligands.
2. The pyridine ring in each ligand is coordinated with the iridium ion through carbon and nitrogen atoms to form a stable chelate ring structure.
3. The two fluorine atoms are located at the 4th and 6th positions of the benzene ring, which enhances the electronic properties of the complex.

Uses：

1. Organic light-emitting diodes: Due to their high luminous efficiency and excellent color purity, they are widely used in displays and lighting equipment.
2. Light-emitting diodes: They also perform well in other light-emitting diode applications, especially in situations where high efficiency and stable light emission are required.
3. Optoelectronic devices: Due to their stable optical and electronic properties, they are also of interest in optoelectronic devices, such as photovoltaic cells and light sensors.

1. This compound has not been subjected to large-scale toxicity studies, and the specific toxicity information is still unclear.
2. As with any chemical substance, safe operating procedures should be followed during operation to avoid contact with skin, eyes, and inhalation of its dust.
3. In the laboratory, appropriate protective measures should be used, such as wearing gloves and goggles.
