This paper describes a new technique entitled scanning differential electrochemical mass spectrometry (SDEMS) that combines a quadrupole mass spectrometer with a membrane-covered capillary inlet and a high resolution positioning system that is designed to perform spatial mapping in solution near an electrode interface. Potential applications of this technique include the local characterization of anode catalysts for fuel cells as well as a range of analytical measurements and combinatorial screening studies. The capabilities of this technique are demonstrated by monitoring product evolution in several model electrocatalytic reactions, including the hydrogen evolution reaction, carbon monoxide oxidation, and the direct oxidation of methanol on platinum and platinum-ruthenium electrodes. The inlet of the SDEMS is based upon a small diameter capillary tube to which a nanoporous, hydrophobic membrane is attached. The capillary inlet is positioned near a substrate electrode using a three-dimensional positioning system. The effect of capillary substrate separation and substrate current on the sensitivity and time response of mass spectrometer’s ion current are illustrated during hydrogen evolution at a platinum substrate. The sensitivity is demonstrated further by detection of carbon dioxide evolution during the oxidation of a monolayer of carbon monoxide adsorbed on platinum. The ability to address more complex reactions involving complete and partial oxidation products is illustrated with methanol oxidation. In order to demonstrate the ability of this technique to perform spatial mapping, an eight-element band electrode was interrogated for hydrogen evolution and methanol oxidation. Detection of ion currents associated with complete and partial oxidation products of methanol on a set of platinum-ruthenium band electrodes illustrates the ability of this method to spatially discriminate between various reactive sites on a surface, which has potential utility in analytical characterization as well as application as a screening tool in combinatorial catalysis studies.

1H NMR spectroscopy and viscosity measurements have been used to study the oligonucleotide binding of the Delta-and Lambda-enantiomers of the metal complex [Ru(dmphen)2dpq]2+ (dmphen = 2,9-dimethyl-1,10-phenanthroline and dpq = dipyrido[3,2-f:2?,3?-h]quinoxaline). The addition of either enantiomer to d(GTCGAC)2 induced large upfield shifts and significant broadening for the hexanucleotide imino and metal complex dpq resonances. These data coupled with the observed increase in the melting transition midpoint of the hexanucleotide duplex upon addition of either enantiomer suggests that both Delta- and Lambda-[Ru(dmphen)2dpq]2+ bind by intercalation. A significant number of metal complex to hexanucleotide NOE contacts were observed in NOESY spectra of d(GTCGAC)2 with added Delta- or Lambda-[Ru(dmphen)2dpq]2+. The observed intermolecular NOEs were consistent with both enantiomers intercalating between the G4A5 bases of one strand and the T2C3 bases of the complementary strand. Intermolecular NOEs from the dmphen protons were only observed to protons located in the hexanucleotide minor groove. Alternatively, NOE contacts from the dpq protons were observed to both major and minor groove protons. The NOE data suggest that the dpq ligand of the Delta-enantiomer intercalates deeply into the hexanucleotide base stack while the Lambda-enantiomer can only partially intercalate. Viscosity measurements were consistent with the proposed intercalation binding models. The addition of the Delta-enantiomer increased the relative viscosity of the DNA solution, while a decrease in the relative viscosity of the DNA was observed upon addition of the Lambda-metal complex. These results confirm our proposal that octahedral metallointercalators can intercalate from the minor groove. In addition, the results demonstrate that the left-handed enantiomer of [Ru(dmphen)2dpq]2+ prefers to intercalate from the narrow minor groove despite only being able to partially insert a polycyclic aromatic ligand into the DNA base stack.

The RuCl3 and RuO2*nH2O catalyzed oxidation of alkanes, aromatic fatty acids, alcohols, citronellol and hydroxycitronellol by NaOCl was studied in the diphase system CCl4-aqueous NaOCl at pH 13-13.5.At 60 – 65 deg C, using 1-2 mole percent of catalyst and a 1.5-fold molar excess of NaOCl, primary alkanols (hexanol-1, 2-ethylhexanol-1, decanol-1, hexadecanol-1) benzyl and 3-phenylpropyl alcohols, and hydroxycitronellol are converted to the corresponding aldehydes with a selectivity of 70-90percent and a yield of over 75percent.

Catalytic performances of bis- and tris(bipyridine) Ru complexes grafted on mesoporous FSM-16 were studied in the photooxidation of benzene to phenol using H2O2 as an oxidant. [Ru(bpy)3]Cl2/FSM-16 showed a high activity under UV-irradiation, and the turnover number (TON) of phenol was 430 based on Ru in 24 h, and the selectivity to phenol among the products was 98%. Non-grafted [Ru(bpy)3]Cl2 complex gave a phenol TON of 170, thus demonstrating the promotion effect of grafting [Ru(bpy)3]Cl2 on FSM-16. The hydroxylation of benzene to phenol by [Ru(bpy)3]Cl2/FSM-16 slightly occurred in the dark (TON = 34 in 24h), but the irradiation remarkably increased the TON of phenol by a factor of 13. The absorption peak of [Ru(bpy)3]Cl2 in the UV-VIS spectroscopy decreased under the reaction conditions; however, the recovered catalyst showed almost the same activity for phenol formation in the repeated runs. It is proposed that coodinatively unsaturated [Ru(bpy)n]2+ (n = 1,2) are generated by the UV-irradiation to [Ru(bpy)3]Cl2 on FSM-16. These species activate H2O2 to give an OH radical that attacks benzene as in the Fenton-type mechanism. Grafting of the Ru complex on FSM-16 may enhance the reaction of a hydroxycyclohexadienyl radical with the isolated Ru center.

A new dyad and two triad chromophore compounds containing coumarin, Ru(II) and Os(II) terpyridine-type complexes were synthesized. The dyad is composed of coumarin and Os(II) units, while the triads are composed of coumarin, Ru(II) and Os(II) units. One of the triads has a phenylene spacer to connect the Ru(II) unit and the Os(II) unit, while the other has an azo moiety. Energy transfer in these multichromophoric systems has been probed by electronic absorption and luminescence spectroscopy. The switching behavior of photo-induced energy transfer by redox stimuli in the latter triad has been examined. Photophysical and electrochemical analysis indicates that the contribution of the energy transfer from the coumarin chromophores and the Ru(II) center to the Os(II)-centered emission in the ‘switch-on state’ is estimated to be about 70%. This contribution is larger than that in the previously reported Ru(II)/Os(II) dyad system, which was evaluated to be 40%. Thus, it is concluded that an improved switching of directional energy transfer has been achieved from the coumarin moiety to the Os(II) center in this new triad chromophore system.

This paper describes the systematic preparation and characterization of new families of triple-decker sandwich complexes incorporating formal cyclo-Et2C2B3H3(4-) bridging ligands, including the first species of this class containing second- or third-row transition metals.Complexes of general formula (L)M(Et2C2B3H3)M'(L) (M = Ru, Os; M’ = Co, Ru; L = cymene , Cp, or C5Me5) were obtained in stepwise fashion via (1) synthesis of closo-(L)M(Et2C2B4H4) metallacarboranes, (2) “decapitation” (apex BH removal) of these complexes to give nido-(L)M(Et2C2B3H5), (3) bridge deprotonation to form the corresponding mono- or dianion, and (4) reaction of the anion with an arene metal halide to generate the desired triple-decker compound.In addition, the cobalt-iron triple-decker CpCo(Et2C2B3H3)FeCp was prepared via treatment of (eta6-C8H10)Fe(Et2C2B3H4)(1-) with Na(1+)Cp(1-) and CoCl2 followed by air oxidation.The reaction of (CO)3RuCl2 with (C5Me5)Co(Et2C2B3H3)(2-) gave the “pseudo-triple-decker” complex (C5Me5)Co(Et2C2B3H3)Ru(CO)3.The triple-deckers, especially those containing osmium, are susceptible to chlorination by RuCl3, OsCl3, or dichloromethane, forming exclusively the 4-chloro derivatives.All of the characterized triple-decker complexes are air-stable crystalline solids (except for the osmium-ruthenium species, which are air sensitive) and have been structurally characterized from their (11)B and (1)H NMR, infrared, visible-UV, and unit- and high-resolution mass spectra, further supported by X-ray crystallographic analyses of (cymene)Ru(Et2C2B3H3)Ru(cymene) (10) and CpCo(Et2C2B3H3)Ru(cymene) (11a).Crystal data for 10: mol wt 561.13; space group PI; Z = 2; a = 10.409(3), b = 11.268(5), c = 12.002(4) Angstroem; alpha = 96.16(3), beta = 99.49(2), gamma = 106.69(3) deg; V = 1312(2) Angstroem3; R = 0.043 for 4777 reflections having F02 > 3?(F02).Crystal data for 11a: mol wt 476.92; space group P21/c; Z = 4; a = 8.808(6), b = 17.708(8), c = 14.194(8) Angstroem; beta = 103.50(4) deg; V = 2153(4) Angstroem3; R = 0.058 for 3289 reflections having F02 > 3?(F02).
