One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Product Details of 1271-51-8, In homogeneous catalysis, catalysts are in the same phase as the reactants. In a article, mentioned the application of 1271-51-8, Name is Vinylferrocene, molecular formula is C12H3Fe
Closely spaced 0.2-1 num, Au microelectrodes (50 num long, 1-2 num wide, and 0.1 num thick) on Si3N4 can be functionalized with poly (viniylferrocene), PVFc +/0, or with an N,N’-dibenzyl-4,4′-bipyridinium-based polymer, (BPQ2+/+)n’ derived from hydrolysis of N,N’-bis<(p-trimethoxysilyl)benzyl>-4,4′-bipyridinium (I).Two- or eight-microelectrode arrays have been functionalized with PVFc+/0 or (BPQ2+/+)n.Adjacent microelectrodes can be connected with either polymer in the sense that net current can pass from one microelectrode to another, through the polymer,when one electrode is held at a potential where the polymer is oxidized and the other electrode is held at a potential where the polymer is reduced.From such steady-state current an estimate of the diffusion coefficient for charge transport, DCT, in the polymer can be made; values in the range 10-9 – 10-10 cm2/s are found and accord well with earlier measurements of DCT for the polymers studied.A two-terminal diode can be fabricated by coating one electrode with (BPQ2+/+)n and an adjacent electrode with PVFc+/0 such that there is a connection between the microelectrodes via the (BPQ2+/+)n/PVFc+/0 contact.Current passes when the applied potential is such that the negative lead is attached to the (BPQ2+/+)n-coated electrode and the positive lead is attached to the PVFc+/0-coated electrode.When the applied potential approaches the difference in the Eo’s of the two polymers, current flows with the crucial feature being a downhill (by ca. 0.9 V) cross redox at the (BPQ2+/+)n/PVFc+/0) interface, BPQ+ + Fc+ –> BPQ2+ +Fc0.Current does not flow between the microelectrodes when the applied is in the opposite sense, because the reaction BPQ2+ + Fco –> BPQ+ + Fc+ is uphill by ca. 0.9 V.The switching time of a microelectrochemical diode is controlled by the time required to oxidize and reduce the polymers.
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
