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.

Synthesis and characterization of Ir and Rh complexes supported on layered K4Nb6O17as a heterogeneous photocatalyst for visible-light-induced hydrogen evolution

Immobilization of photosensitizer cyclometalated iridium(III) ([Ir(ppy)2(bpy)]+) and proton reduction catalyst tris(2,2′-bipyridyl) rhodium(III) ([Rh(bpy)3]3+) complexes onto layered niobate (K4Nb6O17) has been achieved with the aim of developing a photocatalyst for H2production under visible light irradiation. Ir LIII-edge and Rh K-edge X-ray absorption fine structure measurements suggest that the Ir and Rh complexes are easily immobilized with little effect on the surrounding ligand structure. The photoluminescence emission of the immobilized Ir complex near 550 nm decreases with increasing amounts of adjacent Rh complex, suggesting direct electron transfer from Ir to Rh. The Ir-Rh/K4Nb6O17acts as a heterogeneous photocatalyst enabling both visible light sensitization and H2production from an aqueous solution without an electron relay reagent. Leaching and agglomeration of the active metal complexes are not observed after catalytic reactions, and the recovered photocatalyst can be repeatedly recycled without deterioration in its catalytic activity. Moreover, use of exfoliated K4Nb6O17nanosheets is proven to significantly enhance photocatalytic activity.

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.

Anion-mediated encapsulation-induced emission enhancement of an IrIIIcomplex within a resorcin[4]arene hexameric capsule

Understanding of encapsulation processes in confined inner spaces of self-assembled hosts is important for the rational creation of supramolecular systems showing unusual reactivities and physical properties through molecular recognition. Herein we report the formation of luminescent supramolecular host-guest complexes consisting of a hydrogen-bonded resorcin[4]arene hexameric capsule and a variety of emissive Ir complex salts. The Ir complexes, accompanied by small counter anions (Cl-, Br-, NO2-, I- and NO3-), are trapped effectively to show large encapsulation-induced emission enhancement (EIEE) behavior, while Ir complexes having large counter anions (ClO4-, PF6- and OTf-) are not stabilized within the capsule, suggesting that the Ir complex cation is trapped together with its counter anion to form an ion-pair in the capsule. Hydrogen-bonding capabilities of the counter anions also contribute to stabilize host-guest association, because the counter anions trapped within the capsule were in contact with the hydrophilic surfaces of the capsule.
