The determination of electrochemical reactivity and sustainability on individual hyper-stoichiometric UO2+x grains by Raman microspectroscopy and scanning electrochemical microscopy

Using scanning electrochemical microscopy and Raman microspectroscopy, we have successfully observed four distinct defect structures in hyper-stoichiometric UO2+x and demonstrated the relationships between the defect structures and their ability to sustain cathodic reduction processes. When only random point defects are present, the initially inert surface is enhanced by oxidation of the UO2+x. However, when the UO2+x is already extensively oxidized and cuboctahedral clusters are present, further oxidation reduces the surface reactivity. At intermediate levels of stoichiometry corresponding to Willis clusters the surface appears to be reversibly oxidizable.

The alpha-alkylation of ketones with alcohols in pure water catalyzed by a water-soluble Cp?Ir complex bearing a functional ligand

A water-soluble dinuclear Cp?Ir complex bearing 4,4?,6,6?-tetrahydroxy-2,2?-bipyrimidine as a bridging ligand was found to be a highly effective catalyst for the alpha-alkylation of ketones with alcohols in pure water. In the presence of catalyst (0.5 mol%), a series of desirable products were obtained with high reaction economy under environmentally benign conditions. The importance of the hydroxy group in the ligand for catalytic hydrogen transfer was confirmed by mechanism experiments. Furthermore, the application of this catalytic system for the synthesis of a biologically active molecule donepezil in pure water has been accomplished. Notably, this research would facilitate the progress of C-C bond-forming reactions in water catalyzed by water-soluble metal-ligand bifunctional catalysts.

Inhibition of cancer derived cell lines proliferation by synthesized hydroxylated stilbenes and new ferrocenyl-stilbene analogs. Comparison with resveratrol

Further advances in understanding the mechanism of action of resveratrol and its application require new analogs to identify the structural determinants for the cell proliferation inhibition potency. Therefore, we synthesized new trans-resveratrol derivatives by using the Wittig and Heck methods, thus modifying the hydroxylation and methoxylation patterns of the parent molecule. Moreover, we also synthesized new ferrocenylstilbene analogs by using an original protective group in the Wittig procedure. By performing cell proliferation assays we observed that the resveratrol derivatives show inhibition on the human colorectal tumor SW480 cell line. On the other hand, cell viability/cytotoxicity assays showed a weaker effects on the human hepatoblastoma HepG2 cell line. Importantly, the lack of effect on non-tumor cells (IEC18 intestinal epithelium cells) demonstrates the selectivity of these molecules for cancer cells. Here, we show that the numbers and positions of hydroxy and methoxy groups are crucial for the inhibition efficacy. In addition, the presence of at least one phenolic group is essential for the antitumoral activity. Moreover, in the series of ferrocenylstilbene analogs, the presence of a hidden phenolic function allows for a better solubilization in the cellular environment and significantly increases the antitumoral activity.

Dye regeneration kinetics in dye-sensitized solar cells

The ideal driving force for dye regeneration is an important parameter for the design of efficient dye-sensitized solar cells. Here, nanosecond laser transient absorption spectroscopy was used to measure the rates of regeneration of six organic carbazole-based dyes by nine ferrocene derivatives whose redox potentials vary by 0.85 V, resulting in 54 different driving-force conditions. It was found that the reaction follows the behavior expected for the Marcus normal region for driving forces below 29 kJ mol-1 (delta = 0.30 V). Driving forces of 29-101 kJ mol-1 (delta = 0.30-1.05 V) resulted in similar reaction rates, indicating that dye regeneration is diffusion controlled. Quantitative dye regeneration (theoretical regeneration yield 99.9%) can be achieved with a driving force of 20-25 kJ mol-1 (delta ? 0.20-0.25 V).

Thiomethoxychalcone-functionalized ferrocene ligands as selective chemodosimeters for mercury(II): Single-crystal X-ray structural signature of the [Hg8(mu8-S)(SCH3)12] 2+ cluster

Thiomethoxychalcone-based ligands bis[3,3-bis(methylsulfanyl)]-1,1?- eta5-ferrocenyl-2-propen-1-one (L1), 3,3-bis(methylsulfanyl)-1-eta5-ferrocenyl-2-propen-1-one (L 2), and 3-methylsulfanyl-3-sulfanyl-1-eta5-ferrocenyl-2- propen-1-one (L3) have been synthesized on the ferrocene backbone by varying the number of chalcone arms and thiomethoxy substitutents. The single-crystal X-ray crystallographic analyses of all three ligands are reported in which crystals of L1 were obtained as both syn and anti conformers and showed the conformational freedom of the two cyclopentadienyl (Cp) units. L1-L3 are studied extensively toward their applicability in the colorimetric sensing of metal ions in solution. The solution-state study of mono- and bis(thiomethoxy)ferrocenylchalcone- functionalized ligands L1 and L2 showed selective colorimetric sensing for Hg2+ over Li+, Na+, Ca2+, Mg2+, Cr2+, Mn2+, Fe 2+, Co2+, Ni2+, Cu2+, Zn 2+, Cd2+, and Au3+ in acetonitrile. In both cases, a selective color change from orange to purple was observed with Hg 2+ and the resultant solution showed the appearance of a new peak at 565 nm (epsilon = 3920 M-1 cm-1) for L1 and 600 nm (epsilon = 1140 M-1 cm-1) for L2 in the UV/vis experiments. The UV/vis titration profiles of L1 and L 2 indicate the formation of 2:1 (L1/Hg2+) and 1:1 (L2/Hg2+) initial complexations in solution. On the other hand, L3 with thiomethoxy- and thiol-functionalized ferrocenylchalcone showed no appreciable color change with Hg2+ under the same experimental conditions. Attempts were made to isolate single crystals of the resulting purple solution obtained in the cases of L1 and L2 with Hg2+. In both cases, crystals suitable for a single-crystal X-ray diffraction study were isolated in very low yield by a layer diffusion technique. The single-crystal structural investigations demonstrated the formation of a sulfide-encapsulated mercury thiolate cuboctahedron cluster, [Hg8S(SCH3)12] 2+, upon a selective chemodosimetric desulfurization reaction between Hg2+ and L1 or L2. Cyclic voltammetric studies also support the Hg2+-induced cleavage of thiomethoxy groups.

Preparation and characterization of modified electrode by self-assembling ferrocene derivative

Ferrocenylmethy 1,2-dithiolane-3-pentanoate, which can be used to modify a gold electrode surface, was prepared by a condensation reaction with hydroxymethylferrocene and 1,2-dithiolane-3-pentanoic acid (D, L-alpha-lipoic acid). The condensation product has an 1,2-dithiolane ring which adheres to gold surfaces and a ferrocenyl group which is a redox site. The ferrocene rings on the modified electrode were electroactive in both acetonitrile and aqueous media.
