A new series of donor-bridge-acceptor (D-B-A) compounds consisting of pi-conjugated oligofluorene (oFL) bridges between a ferrocene (Fc) electron-donor and a fullerene (C60) electron-acceptor have been synthesized. In addition to varying the length of the bridge (i.e., mono- and bi-fluorene derivatives), four different ways of linking ferrocene to the bridge have been examined. The Fc moiety is linked to oFL: 1) directly without any spacer, 2) by an ethynyl linkage, 3) by a vinylene linkage, and 4) by a p-phenylene unit. The electronic interactions between the electroactive species have been characterized by cyclic voltammetry, absorption, fluorescence, and transient absorption spectroscopy in combination with quantum chemical calculations. The calculations reveal exceptionally close energy-matching between the Fc and the oFL units, which results in strong electronic-coupling. Hence, intramolecular charge-transfer may easily occur upon exciting either the oFLs or Fcs. Photoexcitation of Fc-oFL-C60 conjugates results in transient radical-ion-pair states. The mode of linkage of the Fc and FL bridge has a profound effect on the photophysical properties. Whereas intramolecular charge-separation is found to occur rather independently of the distance, the linker between Fc and oFL acts (at least in oFL) as a bottleneck and significantly impacts the intramolecular charge-separation rates, resulting in beta values between betaCS 0.08 and 0.19 A-1. In contrast, charge recombination depends strongly on the electron-donor-acceptor distance, but not at all on the linker. A value of betaCR (0.35±0.01 A-1) was found for all the systems studied. Oligofluorenes prove, therefore, to be excellent bridges for probing how small structural variations affect charge transport in D-B-A systems. Finely tuned transfer: Chemical modification of the oligo-fluorene linkers between Fc and C60 units enables fine-tuning of photoinduced charge-transfer processes in new donor-bridge-acceptor conjugates (see illustration).

Extensive TDDFT calculations with various combinations of functionals are carried out to compute low-lying excited states of ferrocene. The combined functional and basis set approach TD-PBE0/6-311++G(d,p) is found to be well-behaved in the calculation of excited states. This choice of functional/basis set can give correct ground-state geometries, excitation energies, absorption spectra, and correct symmetry sequence of low level unoccupied molecular orbitals. This method is applied to the calculation of excitation energies of bis(benzene)chromium and four derivatives of ferrocene and the results are accurate within 0.3 eV. The current study implies that the combination TD-PBE0/6-311++G(d,p) can be used to compute excited state properties of other transition metal complexes.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis. We will look forword to the important role of 1271-51-8, and how the biochemistry of the body works.Application of 1271-51-8

A carbon microfiber (7 mum diameter) is employed herein as an electroanalytical sensor. The fabricated sensor is cheap, is disposable, and requires only 150 muL of samples. The carbon fiber is surface-mounted onto an inert surface to overcome the problems of the fragility of the microwire and the possible interference of convective force due to the nonrigid nature of the wires, as well as to improve the reproducibility in length and the amperometric responses. As the cylindrical electrode is supported on a surface, the diffusion of redox-active species to the electrode is partially blocked by the substrate. A theoretical model is developed to account for this hindered diffusion. The mass-transport regime is altered from “linear” at very short time, where the amperometric responses of the supported microwire closely resemble that of an isolated free-standing cylinder (current alpha electrode area), to “convergent” at long time where its response now tends toward that of a hemicylinder of equal radius. The model is validated using chronoamperometry and cyclic voltammetry of an ideal outer-sphere redox probe, reversible ferrocene methanol oxidation. The fabricated microwire electrode is further applied to the system of irreversible 2-nitro-5-thiobenzoate oxidation used in the detection of reduced glutathione (GSH). The microwire electrode shows significantly higher ratio of Faradaic to non-Faradaic currents as compared to microdisk, macrodisk or carbon nanotube modified electrodes. Using the fabricated microwire, GSH can be detected with the sensitivity of 0.7 nA muM-1 and the limit of detection of 0.5 muM (3 sB/m). (Figure Presented).

A series of donor-acceptor ferrocenyl substituted bisthiazoles 3-8 were designed and synthesized by the Pd-catalyzed Suzuki, Heck, and Sonogashira cross-coupling reactions. Their photophysical, electrochemical and computational studies reveal strong donor-acceptor interactions. The photonic and electrochemical studies show that the ferrocenyl bisthiazoles with vinyl linkage ferrocenyl-bisthiazole 4, show better electronic communication compared to rest of the ferrocenyl bisthiazoles. The time dependent density functional theory (TD-DFT) calculation at B3LYP on the ferrocenyl substituted bisthiazoles 3-5 was performed, in which the ferrocenyl-bisthiazole 4 shows strong donor-acceptor interactions compared to the Fc-bisthiazoles 3 and 5. The thermal stability of the ferrocenyl substituted bisthiazoles 3-8 is reported, in which Fc-bisthiazole 8 shows high thermal stability. The single crystal structures of ferrocenyl-bisthiazoles 3 and 5 are reported.

The direct high-yield synthesis without solvent and catalyst, under mild conditions, of eleven novel mono substituted ferrocenylmethyl ethers and amine derivatives from ferrocenemethanol and vicinal oxygenated alcohols and amines is here reported. The peculiar ability of these classes of non acidic compounds to favor the dehydrative nucleophilic substitution is attributed to the presence of vicinal oxygen atoms to the reactive group able to build a hydrogen bonding network with the reactant. The role of carbon dioxide and hexafluoroisopropanol was investigated to support the hypothesis that a template catalysis effect is occurring. The in vitro anti-fungal activity of some of these derivatives was tested on two plant fungi, Botrytis cinerea and Penicillium species, with moderate activity.

The catalytic activity of low-dimensional electrocatalysts is highly dependent on their local atomic structures, particularly those less-coordinated sites found at edges and corners; therefore, a direct probe of the electrocatalytic current at specified local sites with true nanoscopic resolution has become critically important. Despite the growing availability of operando imaging tools, to date it has not been possible to measure the electrocatalytic activities from individual material edges and directly correlate those with the local structural defects. Herein, we show the possibility of using feedback and generation/collection modes of operation of the scanning electrochemical microscope (SECM) to independently image the topography and local electrocatalytic activity with 15-nm spatial resolution. We employed this operando microscopy technique to map out the oxygen evolution activity of a semi-2D nickel oxide nanosheet. The improved resolution and sensitivity enables us to distinguish the higher activities of the materials? edges from that of the fully coordinated surfaces in operando. The combination of spatially resolved electrochemical information with state-of-the-art electron tomography, that unravels the 3D complexity of the edges, and ab initio calculations allows us to reveal the intricate coordination dependent activity along individual edges of the semi-2D material that is not achievable by other methods. The comparison of the simulated line scans to the experimental data suggests that the catalytic current density at the nanosheet edge is ?200 times higher than that at the NiO basal plane.

The enantiomerically pure dibromoferrocene 3 [(Sp,S p)-1,1?-dibromo-2,2?-di(isopropyl)ferrocene], equipped with two iPr groups in alpha positions, was prepared using known “Ugi amine” chemistry. Species 3 was targeted in order to gain access to new [1]ferrocenophanes ([1]FCPs) to be used as monomers for ring-opening polymerization. The iPr groups on the sandwich unit were introduced to stabilize bridging moieties, as well as to increase solubilities of targeted metallopolymers. The planar chiral dibromide 3 can quantitatively be lithiated at 0 C [2 equiv nBuLi, hexanes/thf (9:1), 30 min]. Salt-metathesis reactions with respective element dichloride species gave chiral [1]FCPs with a variety of bridging moieties [ERx=Ga[2-(Me2NCH 2)C6H4] (4 a), SiMe2 (4 b), SntBu2 (4 c), BNiPr2 (4 d)]. The new [1]FCPs were fully characterized including single-crystal X-ray analysis. The stabilizing iPr groups on the Cp rings increase the thermal stabilities of 4 b-d compared to known [1]FCPs, equipped with the same bridging moieties. All three compounds 4 b-d are volatile and could be isolated by vacuum sublimation. Our new approach to [1]FCPs has the potential to overcome many of the existing difficulties in ferrocenophane chemistry, such as limited stability of starting monomers and low solubilities of resulting polyferrocenes. Closing the gap: The preparation of [1]ferrocenophanes with a variety of bridging elements was accomplished by using chiral ferrocene derivatives (see scheme). The isopropyl groups on the sandwich unit serve as protective and solubilizing moieties. The new synthetic approach is superior to the common synthesis of [1]ferrocenophanes, when dilithioferrocene-tmeda is used as the starting material. Copyright
