Recent developments toward high-energy-d. all-organic redox flow batteries suggest the advantageous use of mols. exhibiting multielectron redox events. Following this approach, organic anolytes are developed that feature multiple consecutive one-electron reductions These anolytes are based on N-methylphthalimide, which exhibits a single reversible reduction at a low potential with good cycling stability. Derivatives with two or three imide groups were synthesized to enable multielectron reduction events. By incorporating suitably designed side chains, a volumetric capacity of 65 Ah/L is achieved in electrolyte solutions Bulk-electrolysis experiments and UV-vis-NIR absorption spectroscopy revealed good cycling stability for the first and second reduction of monoamides and diimides, resp., but a loss of stability for the third reduction of triimides. We identify N-2-pentyl-N’-2-(2-(2-methoxyethoxy)ethoxy)ethylaminepyromellitic diimide as a very promising multielectron anolyte with an excellent volumetric capacity and superior cycling and shelf-life stability compared to monoimides and triimides. The outstanding performance of this anolyte was demonstrated in proof-of-principle redox flow batteries that reach an energy d. of 24.1 Wh/L. This study involved multiple reactions and reactants, such as 2-Methoxyethylamine (cas: 109-85-3Recommanded Product: 109-85-3).
2-Methoxyethylamine (cas: 109-85-3) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Recommanded Product: 109-85-3
