Tailoring molecular permeability of nanochannel-micelle membranes for electrochemical analysis of antioxidants in fruit juices without sample treatment

Antioxidants are widely found or used in food, pharmaceutical, and cosmetics industries; thus, rapid and sensitive detection of antioxidants is of great interest. The present work reports a simple and fast electrochemical method for direct analysis of antioxidants in fruit juices by modulating the permeability of mesochannels on the electrode surface. This goal was achieved by growing vertical silica mesochannel array (SMA) with a channel diameter of 2-3 nm on the indium tin oxide (ITO) electrode surface using the cylindrical micelles (CMs) as the template. As-prepared electrodes, designed as CM@SMA/ITO, are only permeable to lipophilic antioxidants, e.g., retinol, with the hydrophobic hydrocarbon cores of CMs. After excluding CMs from silica mesochannels, the ITO electrode modified with bare SMA, namely SMA/ITO, possesses a high density of silanol groups on the channel wall and thus is only permeable to hydrophilic antioxidants, such as ascorbic acid (AA). Two types of sensors allowed the selective analyses of retinol and AA in buffer solutions and demonstrated a wide linear range for retinol (1-60 muM) and AA (10-2000 muM), respectively, and a low detection limit (0.65 muM for retinol and 0.52 muM for AA). Moreover, the SMA/ITO electrode can selectively determine the concentration of AA in orange juice. The CM@SMA/ITO electrode can measure the sum activity of lipophilic antioxidants, such as retinol, alpha-tocopherol, and others possibly coexisting, in carrot juice. In addition, the ultrasmall mesochannels and CMs could effectively exclude the access of large substances, rendering an excellent antifouling and anti-interference ability for direct analysis of antioxidants in fruit juices without sample pretreatment.

Triggered Metal Ion Release and Oxidation: Ferrocene as a Mechanophore in Polymers

The introduction of mechanophores into polymers makes it possible to transduce mechanical forces into chemical reactions that can be used to impart functions such as self-healing, catalytic activity, and mechanochromic response. Here, an example of mechanically induced metal ion release from a polymer is reported. Ferrocene (Fc) was incorporated as an iron ion releasing mechanophore into poly(methyl acrylate)s (PMAs) and polyurethanes (PUs). Sonication triggered the preferential cleavage of the polymers at the Fc units over other bonds, as shown by a kinetic study of the molar mass distribution of the cleaved Fc-containing and Fc-free reference polymers. The released and oxidized iron ions can be detected with KSCN to generate the red-colored [Fe(SCN)n(H2O)6?n)](3?n)+ complex or reacted with K4[Fe(CN)6] to afford Prussian blue.

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.

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.
