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.

In a article, mentioned the application of 1273-94-5, Name is 1,1′-Diacetylferrocene, molecular formula is C14H6FeO2

Highly effective asymmetric hydrogenation of various ferrocenyl ketones, including aliphatic ferrocenyl ketones as well as the more challenging aryl ferrocenyl ketones, was realized in the presence of a Ru/diphosphine/diamine bifunctional catalytic system. Excellent enantioselectivities (up to 99.8% ee) and activities (S/C = 5000) could be obtained. These asymmetric hydrogenations provided a convenient and efficient synthetic method for chiral ferrocenyl alcohols, which are key intermediates for a variety of chiral ferrocenyl ligands and resolving reagents.

Chemistry involves the study of all things chemical – chemical processes, Formula: C14H6FeO2, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. In a patent，Which mentioned a new discovery about 1273-94-5

Since oxidation and reduction reactions mainly take place on surfaces, enlarging the specific surface of redox materials is the key to achieving excellent electrochemical performance. In this work, by using silica monolayer colloidal crystal templates (MCCTs), a nanostructured Fc(COCH3)2 film is prepared successfully, and such a nanostructure could exhibit the following unique electrochemical properties: the MCCTs could impede the aggregation tendency of Fc(COCH3)2 and possess high electrochemical activity; Fc(COCH3)2 enlarges the contact area and offers more active sites and faster electronic transmission channels. The structure, optical and electrochemical properties of the nanostructured Fc(COCH3)2 were tested and then compared with those of compact Fc(COCH3)2 films to evaluate the role of the nanoarchitecture. The unique structure design of the Fc(COCH3)2 film enables outstanding performance, showing a large transmittance change (DeltaT) of 37% at 550 nm when switched between 0.5 V and -2.5 V, which is approximately ninefold higher than that of the compact Fc(COCH3)2 film (approximately 4%). Response times of coloration and bleaching are found to be only 16.15 s and 5.56 s. Furthermore, the nanostructured Fc(COCH3)2 film shows much better cycling stability than the compact one. The results indicate that the nanostructure could significantly improve the electrochemical performance of the Fc(COCH3)2 film due to the increase in electrochemical active sites and the enhancement of the “D-to-A” redox switch of ferrocene.

Reference of 1271-48-3, Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas.1271-48-3, Name is 1,1′-Ferrocenedicarboxaldehyde, molecular weight is 242.0516. belongs to iron-catalyst compound, In an Article，once mentioned of 1271-48-3

The compound bis[1,1?-N,N?-(2-picolyl)aminomethyl]ferrocene, L1, was synthesized. The protonation constants of this ligand and the stability constants of its complexes with Ni2+, Cu2+, Zn2+, Cd2+ and Pb2+ were determined in aqueous solution by potentiometric methods at 25C and at ionic strength 0.10 mol dm-3 in KNO3. The compound L1 forms only 1:1 (M:L) complexes with Pb2+ and Cd2+ while with Ni 2+ and Cu2+ species of 2:1 ratio were also found. The complexing behaviour of L1 is regulated by the constraint imposed by the ferrocene in its backbone, leading to lower values of stability constants for complexes of the divalent first row transition metals when compared with related ligands. However, the differences in stability are smaller for the larger metal ions. The structure of the copper complex with L1 was determined by single-crystal X-ray diffraction and shows that a species of 2:2 ratio is formed. The two copper centres display distorted octahedral geometries and are linked through the two L’ bridges at a long distance of 8.781(10) A. The electrochemical behaviour of L1 was studied in the presence of Ni2+, Cu2+, Zn2+, Cd2+ and Pb2+, showing that upon complexation the ferrocene – ferrocenium half-wave potential shifts anodically in relation to that of the free ligand. The maximum electrochemical shift (DeltaE1/2) of 268 mV was found in the presence of Pb2+ followed by Cu2+ (218 mV), Ni 2+ (152 mV), Zn2- (111 mV) and Cd2+ (110 mV). Moreover, L1 is able to electrochemically and selectively sense Cu2+ in the presence of a large excess of the other transition metal cations studied.

Respiration, photosynthesis and peroxidase activities of living spherical samples, such as algal protoplasts, breast cancer spheroids and bovine embryos, were characterized with scanning electrochemical microscopy (SECM). The concentration profile of the metabolic product around the spherical sample was directly measured by scanning with a probe microelectrode. According to the spherical diffusion theory, the total mass transfer rate per spherical sample is linear to the multiplication of the sample radius and the concentration difference between the sample surface and the bulk of the solution. Therefore, the sample radius is a key parameter to assess the viability of the living samples. For example, we investigated the respiration and photosynthesis activities as a function of the size of the protoplast (Bryopsis plumosa). The respiration rate was linear to the cube of the sample radius. On the contrary, the photosynthesis rate was linear to the square of the sample radius, suggesting that the former is controlled by the volume of the protoplast, and the latter is controlled by the surface area of the protoplast. We will also discuss the size-dependent activity of the breast cancer spheroids and the bovine embryos. Furthermore, relations between the sample size, the concentration difference, and the oxygen consumption rate of the cryo-preserved bovine blastocysts were investigated.

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 1273-86-5, and how the biochemistry of the body works.Application of 1273-86-5
