Phosphorescent Cyclometalated Platinum(II) Imidazolinylidene Complexes

Temperature dependence of blue phosphorescent cyclometalated Ir(III) complexes.

The photophysical properties for a series of facial (fac) cyclometalated Ir(III) complexes (fac-Ir(C--N)(3) (C--N = 2-phenylpyridyl (ppy), 2-(4,6-difluorophenyl)pyridyl (F2ppy), 1-phenylpyrazolyl (ppz), 1-(2,4-difluorophenyl)pyrazolyl) (F2ppz), and 1-(2-(9,9'-dimethylfluorenyl))pyrazolyl (flz)), fac-Ir(C--N)(2)(C--N') (C--N = ppz or F2ppz and C--N' = ppy or F2ppy), and fac-Ir(C--C')(3) (C--C' =...

Phosphorescent cyclometalated complexes for efficient blue organic light-emitting diodes

Phosphorescent emitters are extremely important for efficient organic light-emitting diodes (OLEDs), which attract significant attention. Phosphorescent emitters, which have a high phosphorescence quantum yield at room temperature, typically contain a heavy metal such as iridium and have been reported to emit blue, green and red light. In particular, the blue cyclometalated complexes with high ...

Synthetically Tailored Excited States: Phosphorescent, Cyclometalated Iridium ACHTUNGTRENNUNG(III) Complexes and Their Applications

Blue phosphorescent nitrile containing C^C* cyclometalated NHC platinum(II) complexes.

Since C^C* cyclometalated Pt(II) complexes with N-heterocyclic carbene (NHC) ligands have been identified as potential emitter materials in organic light-emitting devices (OLEDs), very promising results regarding quantum yields, colour and stability have been presented. Herein, we report on four nitrile substituted complexes with a chelating NHC ligand (1-(4-cyanophenyl)-3-isopropyl-1H-benzo[d]...

Coumarin-appended phosphorescent cyclometalated iridium(iii) complexes as mitochondria-targeted theranostic anticancer agents.

Theranostic anticancer agents incorporating anticancer properties with capabilities for real-time treatment assessment are appealing candidates for chemotherapy. The design of mitochondria-targeted cytotoxic drugs represents a promising approach to target tumors selectively and overcome resistance to current anticancer therapies. In this work, three coumarin-appended phosphorescent cyclometalat...
