Polytriphenylamine Derivative and Carbon Nanotubes as Cathode Materials for High-Performance Polymer-Based Batteries

Composites of polytriphenylamine (PTPA), its novel derivative poly(4-carbamoyl-N,N-diphenylaniline-2,2,5,5-tetramethyl-pyrrolin-1-oxyl) (PTPA-PO), and multi-walled carbon nanotubes (CNTs) were synthesized by in situ polymerization. The characterization results showed that the CNTs were homogeneously distributed in the polymer matrix and formed a cross-linked conductive network. The electrical properties of PTPA/CNT composites were better than those of traditional acetylene black as conductive agents. Electrochemical tests showed that the initial specific discharge capacity of the PTPA/CNT composites was 107.6 mAh g(-1 )(theoretical capacity of PTPA is 109 mAh g(-1)). Furthermore, further research to increase the specific capacity demonstrated that the as-synthesized polytriphenylamine derivative, PTPA-PO, with a CNT cathode presented two well-defined plateaus and an enhanced discharge capacity of 139.3 mAh g(-1). Additionally, the PTPA-PO/CNT electrode showed superior cycling performance and remained above 90% of the initial capacity after 100 cycles. The enhanced electrochemical performance of PTPA-PO was due to its combination of the conducting polymer PTPA and free radical active site pendant PO, which increased its electrochemical reaction rate, and this composite is a promising material for high-performance polymer-based organic batteries.

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.I hope my blog about 29968-78-3 is helpful to your research. Name: 4-Nitrophenylethylamine hydrochloride.

Synthesis of functionalized pyrrolidin-2-ones and (S)-Vigabatrin from pyrrole

Starting from pyrrole, the novel 3,4-didehydropyrohomoglutamate 8 or (ent)-8 can be efficiently synthesized in up to 91% ee, which can be utilized as a versatile building block toward functionalized pyrrolidin-2-ones. Moreover, (ent)-8 can be readily converted to (S)-Vigabatrin, being an irreversible inhibitor for GABA-T, which is used as adjunctive therapy in patients that suffer from epilepsy.

Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Read on for other articles about 29968-78-3. Application of 29968-78-3.

Sequential activation of a-bonds : Intermolecular cascade annulation with migration and remote functionalization

We demonstrate a new catalytic property of the lanthanide compound CeCl3 center dot 7H(2)O which sequentially activates N-H, sp(2) C-H and sp(3) C-H sigma-bonds at ambient temperature. The powerful catalyst enables selective C-C and C-N bond-forming intermolecular cascade annulation between enamines and diary1-1,2-diketone to afford functionalized 3,3-diaryl-3-pyrrolin-2-ones involving migration of an aromatic ring. We have also initiated a new multicomponent strategy utilizing readily available and inexpensive precursors and environmentally benign CeCl3 center dot 7H(2)O as an efficient catalyst under benign reaction conditions towards direct synthesis of several N-heterocycles including pentasubstituted 2-pyrrolinones and pyrroles. These observations provide new prospects and perspectives in sigma-bond activation process for easy access to functional molecules.

One-Pot Synthesis of B-Aryl Carboranes with Sensitive Functional Groups Using Sequential Cobalt- and Palladium-Catalyzed Reactions

The simple and efficient method was developed for the one-pot synthesis of B-substituted aryl derivatives of ortho-carborane with functional groups sensitive to organolithium and organomagnesium reagents using 9-iodo-ortho-carborane and generated in situ organozinc compounds. The method proposed was used to prepare a series of 9-aryl-ortho-carboranes, including those containing nitrile and ester groups, 9-RC6H4-1,2-C2B10H11 (R = p-Me, p-NMe2, p-OCH2OMe, o-OMe, p-OMe, o-CN, p-CN, o-COOEt, m-COOEt, and p-COOEt). It was demonstrated that the same approach can be used for synthesis of diaryl derivatives of ortho-carborane 9,12-(RC6H4)(2)-1,2-C2B10H10 (R = H, p-Me). The solid-state structures of 9-RC6H4-1,2-C2B10H11 (R = p-NMe2, p-OCH2OMe, o-OMe, o-CN, p-CN, m-COOEt, and p-COOEt) and 9,12-(p-MeC6H4)(2)-1,2-C2B10H10 were determined by single crystal X-ray diffraction.

Ethanol amine functionalized electrospun nanofibers membrane for the treatment of dyes polluted wastewater

This study investigated adsorption kinetics, adsorption equilibrium, and adsorption isotherm of three dyes [i.e., methylene blue (MB), rhodamine-B (RB), and safranin T (ST)] onto polyacrylonitrile (PAN) and ethanolamine (EA) grafted PAN nanofibers (NFs) membranes (EA-g-PAN). The membranes were characterized by field emission scanning electron microscopy (FE-SEM), Fourier-transform infrared spectroscopy (FT-IR) spectroscopy, and Brunauer-Emmet-Teller (BET). FE-SEM showed a smooth morphology for the NFs before and after grafting, while FT-IR confirmed EA grafting into the nitrile group of PAN. The grafting percentage with no change in the physical nature of the membrane was 12.18%. The nitrogen adsorption-desorption isotherms for PAN and EA-g-PAN NFs membranes were similar and classified as a Type IV according to the International Union of Pure and Applied Chemistry. The surface area, pore-volume, and pore size of the EA-g-PAN increased to 21.36 m(2) g(-1), 0.16 cm(3) g(-1), and 304.93 angstrom, respectively. The pores were cylindrical mesopores with bimodal openings, which means that pores were open at both ends. The adsorption of the MB, RB, and ST dyes onto the PAN and EA-g-PAN NFs membranes leveled off at similar to 60 min. The adsorption kinetics showed good fitting to pseudo-second-order kinetic model and multi-step diffusion process. The order of the dye adsorption was PAN < EA-g-PAN. The data were fitted to Langmuir and Freundlich models. The correlation coefficient (r(2)) for Langmuir ranged from 0.940 to 0.995, whereas that for Freundlich ranged from 0.941 to 0.998. After adsorption, FTIR only showed hydrogen bonding between the dyes and the membrane. The reusability experiments showed max desorption for MB (94%), RB (92%), and ST (85%). The EA-g-PAN NFs membrane showed potential for the removal of organic pollutants from the environment.
