Iridium complexes containing three different ligands as white OLED dopants

Previously, we studied the luminescence characteristics of Ir(ppy)2(F2-ppy) and Ir(ppy)2(piq-F), which are heteroleptic iridium complexes involving two kinds of ligands, where F2-ppy, ppy and piq-F represent 2-(2,4-difluoro-phenyl)- pyridine, 2-phenylpyri

Bright sky-blue phosphorescence of [ n -Bu4N][Pt(4,6-dFppy)(CN) 2]: Synthesis, crystal structure, and detailed photophysical studies

This work describes the synthesis, crystal structure, and detailed photophysical studies of [n-Bu4N][Pt(4,6-dFppy)(CN)2] (n-Bu = n-butyl, 4,6-dFppy = (4′,6′-difluorophenyl)pyridinate). The material can easily be prepared in high yiel

Ligand-to-ligand charge transfer in heteroleptic Ir-complexes: Comprehensive investigations of its fast dynamics and mechanism

To gain new insights into ligand-to-ligand charge-transfer (LLCT) dynamics, we synthesised two heteroleptic Ir3+ complexes: (Ir(dfppy)2(tpphz)) and (Ir(dfppy)2(dpq)), where dfppy, tpphz, and dpq are 2-(4,6-difluorophenyl)p

Effects of fluorine substituent on properties of cyclometalated iridium(III) complexes with a 2,2′-bipyridine ancillary ligand

Cationic cyclometalated Ir(III) complexes (Ir1-Ir5) with fluorine-substituted 2-phenylpyridine (ppy) derivatives as C^N cyclometalating ligands and 2,2′-bipyridine (bpy) as the ancillary ligand, have been synthesized and fully characterized. The influences of the number and the position of fluorine atoms at the cyclometalating ligands on the photophysical, electrochemical and oxygen sensing properties of the Ir(III) complexes have been investigated systematically. The introduction of fluorine on the C^N cyclometalating ligands of the complexes results in blue-shifts of the maximum emission wavelengths, and increases in the photoluminescence quantum yields (ΦPL), phosphorescence lifetimes and energy gaps, compared to the non-fluorinated [Ir(ppy)2(bpy)]+PF6? (Ir0). Among them, 2-(2,4-difluorophenyl)pyridine-derived Ir4 shows the maximum blue-shift (514 nm vs. 575 nm for Ir0) and the highest ΦPL (50.8% vs. 6.5% for Ir0). The complex Ir3 with 2-(4-fluorophenyl)-5-fluoropyridine as C^N ligand exhibits the highest oxygen sensitivity and excellent operational stability in 10 cycles within 4000 s.

TRI-(ADAMANTYL)PHOSPHINES AND APPLICATIONS THEREOF

In one aspect, phosphine compounds comprising three adamantyl moieties (PAd3) and associated synthetic routes are described herein. Each adamantyl moiety may be the same or different. For example, each adamantyl moiety (Ad) attached to the phosphorus atom can be independently selected from the group consisting of adamantane, diamantane, triamantane and derivatives thereof. Transition metal complexes comprising PAd3 ligands are also provided for catalytic synthesis including catalytic cross-coupling reactions.
