English Name:(4,4'-Di-tert-butyl-2,2'-bipyridine)bis[2-(pyridin-2-yl)phenyl]iridium(III) hexafluorophosphate

CAS No.:676525-77-2

Aliases:[Ir(dtbbpy)(ppy)2]PF6, Bis[2-(pyridin-2-yl)phenyl](4,4'-di-tert-butyl-2,2'-bipyridine)iridium(III) hexafluorophosphate

Molecular Formula:C40H40F6IrN4P

Physical Properties:Yellow to orange-yellow powder; density approximately 1.5 g/cm³ (estimated); no clear melting point; decomposes above 320 °C. Soluble in polar organic solvents such as acetonitrile, dichloromethane, acetone, and DMF; slightly soluble in methanol and ethanol; practically insoluble in water. The complex features a metal-to-ligand charge transfer (MLCT) triplet excited state, showing strong visible-light absorption and phosphorescence with an emission maximum at approximately 580 nm at room temperature. It has a microsecond-scale excited-state lifetime, good photostability, and is stable to air and moisture.

Uses:This compound is a highly efficient phosphorescent iridium complex widely used in OLED emitting materials, light-emitting electrochemical cells (LECs), and optoelectronic device research. As a photosensitizer and photoredox catalyst, it is commonly applied in photocatalytic organic synthesis, including C–C coupling, C–H functionalization, and atom transfer radical reactions (ATRP). It is also used in bioimaging and luminescent sensing probe studies.
