(4,4'-Di-t-butyl-2,2'-bipyridine)bis[3,5-difluoro-2-(5-trifluoromethyl-2-pyridinyl-κN)phenyl-κC]iridium(III) hexafluorophosphate (CAS 870987-63-6, abbreviated Ir(dF(CF₃)ppy)₂(dtbpy)PF₆) is a cationic iridium(III) complex. It has a molecular formula of C₄₂H₃₄F₁₆IrN₄P (MW 1121.91) and appears as a yellow crystalline solid. With excellent thermal stability and red phosphorescence (600–630 nm), it is widely used as a high-efficiency emitter in OLEDs, plus applications in ECL and photocatalysis. It is soluble in polar organic solvents, sensitive to moisture/oxidants, and requires dry, dark storage.

(4,4'-Di-t-butyl-2,2'-bipyridine)bis[3,5-difluoro-2-(5-trifluoromethyl-2-pyridinyl-κN)phenyl-κC]iridium(III) hexafluorophosphate, commonly abbreviated as Ir(dF(CF₃)ppy)₂(dtbpy)PF₆, is a cationic iridium(III) complex with important photophysical and electrochemical properties.
CAS Number: 870987-63-6
Molecular Formula: C₄₂H₃₄F₁₆IrN₄P
Molecular Weight: 1121.91 g/mol
Appearance: Yellow crystalline solid or powder
Melting Point: >300 °C
The central metal ion is Ir³⁺, coordinated in an octahedral geometry by three chelating ligands.
Two are C^N cyclometalated ligands: 2-(2,4-difluorophenyl)-5-trifluoromethylpyridine (abbreviated as dF(CF₃)ppy), binding to Ir³⁺ via a carbon atom (κC) from the phenyl ring and a nitrogen atom (κN) from the pyridine ring.
One is an N^N bipyridine ligand: 4,4'-di-tert-butyl-2,2'-bipyridine (dtbpy), chelating Ir³⁺ through the nitrogen atoms of the two pyridine rings.
The counterion is hexafluorophosphate (PF₆⁻) to maintain overall electrical neutrality.
Solubility: Well-soluble in polar organic solvents such as dichloromethane, chloroform, and acetonitrile.
Thermal Stability: High rigidity in molecular structure leads to excellent thermal stability, withstanding temperatures above 250 °C under inert atmosphere.
Photoluminescent Properties: Exhibits strong phosphorescent emission in the red region (600–630 nm), with high photoluminescent quantum yield (PLQY) and long emission lifetime.
Electrochemical Properties: Features reversible redox processes and a stable electrochemical window.
OLED Materials: A widely used red phosphorescent emitter in organic light-emitting diodes (OLEDs), suitable for high-efficiency and high-stability red OLED devices.
Other Fields: Applied in electrochemiluminescence (ECL), photocatalysis, and photoelectric conversion due to its balanced charge-transport capabilities.
Stable under dry, dark, and inert gas conditions.
Sensitive to moisture and strong oxidants; avoid use in high-humidity, strong acid, or strong alkali environments.
