Ir^III(C^N)₂(P-donor ligand)Cl-type complexes bearing functional groups and showing aggregation-induced phosphorescence emission (AIPE) behavior for highly efficient OLEDs

Abstract

Based on P-donor ligands of triphenylphosphine and triethylphosphine, a series of IrIII(C^N)(P-donor ligand)Cl-type complexes bearing C^N ligands with functional groups of diphenylamine and carbazole have been successfully prepared. In dilute...

Fluorene-decorated Ir(iii) complexes: synthesis, photophysics and tunable triplet excited state properties in aggregation

“…When complexes Ir1 or Ir2 aggregate, the long alkyl chain introduced into the Ir1 and Ir2 will hinder phosphorescence quenching, which is a result of π-π stacking. Moreover, the introduction of fluorene groups would restrict the intramolecular rotation, 46,47 which will lead to an enhancement of the radiative process and a decrement of the non-radiative process.…”

C–H, N–H, and O–H Bond Activations to Prepare Phosphorescent Hydride-Iridium(III)-Phosphine Emitters with Photocatalytic Achievement in C–C Coupling Reactions

“…High Δ 0 values also prevent ligand dissociations, decreasing possible emitter decomposition chemical pathways . Indeed, a few emitters carrying a coordination sphere formed by a pincer donor of 4e, two phosphines, and a hydride have recently been reported to be particularly efficient members of a small family of phosphine-derived emitters …”
