Electrochemistry and Spectroscopy of Ortho-Metalated Complexes of Ir(III) and Rh(III)

The electrochemical and UV-visible spectroscopic properties of Rh(III) and Ir(III) complexes of the ortho-metalating (NC) ligands, 2-phenylpyridine (ppy) and benzo(h)quinone (bzq), have been studied.Cyclic voltammetric studies of several of the dimeric species, 2, indicate metal-centered oxidation occurs at moderate potentials.Cationic monomers of the type M(NC)2(NN)+ where (NN) = 2,2'-bipyridine or 1,10-phenanthroline have been prepared by reaction of the chelating ligands with the parent dimers.Cyclic voltammetric studies of these monomers indicate that several reversible ligand-centered reductions are generally observed and that the chelating ligand is more easily reduced than is the ortho-metalating ligand.Spectroscopic studies of the mixed ligand monomers indicate that dual emissions from MLCT states associated with the ortho-metalating and chelating ligands occur in the Ir(III) complexes whereas a single emission from a ligand-localized excited state is observed in the Rh(III) complexes.These results are discussed in terms of electronic and nuclear coupling factors analogous to those encountered in descriptions of bimolecular energy and electron-transfer processes.

Iridium and rhodium complexes within a macroreticular acidic resin: A heterogeneous photocatalyst for visible-light driven H2 production without an electron mediator

Direct ion exchange of cyclometalated iridium(III) and tris-2,2′- bipyridyl rhodium(III) complexes, of which the former acts as a photosensitizer and the latter as a proton reduction catalyst, within a macroreticular acidic resin has been accomplished with the aim of developing a photocatalyst for H2 production under visible-light irradiation. Ir L III-edge and Rh K-edge X-ray absorption fine structure (XAFS) measurements suggest that the Ir and Rh complexes are easily accommodated in the macroreticular space without considerable structural changes. The photoluminescence emission of the exchanged Ir complex due to a triplet ligand charge-transfer (3LC) and metal-to-ligand charge-transfer ( 3MLCT) transition near 550 nm decreases with increasing the amount of the Rh complex, thus suggesting the occurrence of an electron transfer from Ir to Rh. The Ir-Rh/resin catalyst behaves as a heterogeneous photocatalyst capable of both visible-light sensitization and H2 production in an aqueous medium in the absence of an electron mediator. The photocatalytic activitity is strongly dependent on the amount of the components and reaches a maximum at a molar ratio of 2:1 of Ir/Rh complexes. Moreover, leaching and agglomeration of the active metal complexes are not observed, and the recovered photocatalyst can be recycled without loss in catalytic activity. Copyright

Performance improvement of yellow emitting electrochemiluminescence devices: Effects of frequency control and coreactant pathway

In this work, we propose an electrochemiluminescence (ECL) luminophore, 2,2′-bipyridylbis(2-phenylpyridine)iridium(III) hexafluorophosphate ([Ir(ppy)2(bpy)][PF6]) (1), emitting yellow-colored light for displaying a variety of ECL colors. The synthesized luminophore 1 is optically and electrochemically analyzed. The ECL electrolytes are very simply composed of 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([EMI][TFSI]), sandwiched between two transparent electrodes used for the devices. The resulting ECL devices are characterized by a low-voltage operation and quick response independent of frequency. We also suggest an efficient method for improving the ECL brightness by incorporating 2,2′-bipyridylbis[2-(2′,4′-difluorophenyl)pyridine]iridium(III) hexafluorophosphate ([Ir(diFppy)2(bpy)][PF6]) (2) as a coreactant. The intensity of the emitted yellow light is doubled, when 60 mol% of 2 is included in the mixed-luminophore system. Additionally, we further enhanced the luminance of yellow light emitting ECL devices by adjusting the frequency of applied AC voltage, leading to ～3.5 times higher brightness at 500 Hz.

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.
