This paper describes the orbital configuration which provides a basis for the understanding of the electronic structure and spectroscopic properties of 17e and 18e FcC2R and FcC4R dyads, where R is H, 1-naphthyl, 9-anthryl, 3-pyrenyl, perylenyl. DFT calculations show that destabilisation of the ferrocenyl pi orbitals upon binding a C{triple bond, long}CR group to a Cp ring leads to the metal-based a1 orbital dropping below the e1-a so that the frontier orbital configuration is (e2? -a, pi)2 (e2? -b,metal)2 (e1? -a, pi)2, (a1, metal)2. The contribution of the aryl group to the pi e2-a and e1-a orbitals varies with the annelation of the ring. The LUMO is aryl based. The calculations are consistent with the spectroscopic data for the 18e species. Oxidation to the 17e cations does not change the orbital configuration but the orbital energies are lowered by the positive charge centred on the Fe. A strongly solvatochromic transition in the near-IR, a signature for the 17e cations, is best described as an LMCT transition but the contribution of C2R and C4R to the donor and acceptor levels depends on the ionization energy of the aryl pi orbital. LMCT energies decrease from FcC2R to FcC4R dyads.

Real time measurement of time-correlated ion transport and volumetric changes in electroactive materials is necessary to understand and model mechanoelectrochemistry. Reversible reduction and oxidation of soft electroactive materials such as conducting polymers result in the deformation of the material due to ion transport into and out of the polymer backbone. In cells, ion transport and volumetric expansion are collectively responsible for homeostasis that is essential for life functions and hence, mechanoelectrochemistry of cells is essential to understand cell and developmental biology. The characterization methods required to investigate mechanoelectrochemistry require nanoscale spatial resolution for the imaging of a redox active site in a polymer or a small group of transmembrane proteins in a single cell. Towards this goal, we present an imaging technique using scanning electrochemical microscopy (SECM) hardware with shear-force (SF) feedback for high bandwidth mechanoelectrochemistry characterization. In this proceedings article, we demonstrate this technique referred to as surface-tracked scanning electrochemical microscopy technique (ST-SECM) that is realized by measuring the structural feedback of the glass electrode to position the electrode in 10s of nanometers above the surface of a polypyrrole membrane doped with dodecylbenzenesulfonate (PPy(DBS)). Two ultra-microelectrodes of controlled dimensions (of 20 mum and 30 mum glass diameter) were fabricated using a hydrofluoric acid etching technique and were used to generate a spatially correlated ion storage map of PPy(DBS). We compare the developed technique to a three-dimensional discrete scan over the surface and show that a ST-SECM technique produces a higher resolution and takes approximately 200 fewer minutes as compared to the conventional technique.

A new method for substitution of a vinylic hydrogen with an alkyl group (a Mizoroki-Heck type transformation) was developed by a titanocene catalyst in the presence of nBuMgCl. This reaction could proceed regio- and stereoselectively under mild conditions to afford E-olefins using primary and secondary alkyl halides. The reactions of aliphatic alkenes, e.g., 1-octene and internal alkenes, were sluggish. When t-alkyl halides were employed, alkylative dimerization of alkenes proceeded exclusively to give symmetrical vic-diarylalkanes. These reactions involved addition of alkyl radicals to arylalkenes to form benzyl radicals as a carbon-carbon bond-forming step. Dimerization of thus formed benzyl radicals afforded symmetrical alkanes and beta-hydrogen elimination from benzyltitanocene intermediates gave alkylated alkenes. A possibility that titanocene activates alkenes as radical accepters was also proposed.

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.Product Details of 1271-51-8

This work focuses on the investigation of the very early stages of the degradation of coil-coated galvanized steel sheet through swelling and blistering during exposure to chloride-containing aqueous solutions and the possible effect of the zinc-based metallic coating on the degradation at these very early stages. Three types of coil-coated steel whose difference was in the zinc-based metallic coating, namely galvanized, galfan and aluzinc, were considered. Scanning electrochemical microscopy (SECM) operating in the feedback mode was employed to image topographic changes when the samples were left at their spontaneous open circuit potential. Swelling of the coating and nucleation of blisters were observed for all the samples when they were exposed to naturally aerated 0.1 M KCl solution within 24 h exposure. Conversely, featureless and flat surfaces were found when the samples were either exposed to 0.1 M K2SO4 or to 10 mM KCl. For chloride concentrations of 0.1 M and above the chloride ions were observed to promote coating degradation nearly immediately upon immersion in the electrolyte.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. In my other articles, you can also check out more blogs about 1273-86-5
