Name: 1-Methyl-4-piperidoneIn 2020 ,《Chemically stable poly(meta-terphenyl piperidinium) with highly conductive side chain for alkaline fuel cell membranes》 appeared in Journal of Membrane Science. The author of the article were Lu, Chuanrui; Long, Chuan; Li, Yunxi; Li, Ziming; Zhu, Hong. The article conveys some information:
Poly(arylene piperidine)s (PAPs) backbones, which do not contain unstable ether bonds, was synthesized by one-pot, metal-free superacid-catalyzed polymerization for anion exchange membranes (AEMs) preparation Meta-terphenyl as a monomer of polymer to regulate the morphol. and properties of AEM was also used due to its spatially torsional configuration instead of the recently reported linear structure of meta-terphenyl. Long flexible hydrophilic chains were grafted onto poly(meta terphenyl piperidinium) (m-PTP) backbone to form four cationic functionalized side chains, promoting efficient transfer of OH- and optimizing the hydrophilic/hydrophobic microphase separation structure. The resulting AEM shows a high ion conductivity of 164 mS/cm (m-PTP-TFPE-21) at 80°C. Furthermore, stable piperidine cation and long alkyl spacer chain contributed to the excellent alkali stability of m-PTP-TFPE-TQA membrane which shows only 11.67% and 12.73% degradation in ion conductivity and IEC, resp., after soaking in 2 M NaOH at 80°C for 1500 h. The peak power d. of the H2/O2 single cell using m-PTP-TFPE-14 is 269 mW/cm2 at a c.d. of 540 mA/cm2 at 80°C. The results came from multiple reactions, including the reaction of 1-Methyl-4-piperidone(cas: 1445-73-4Name: 1-Methyl-4-piperidone)
1-Methyl-4-piperidone(cas: 1445-73-4) is a member of piperidine. Piperidine is ubiquitous structural motif widely occurred in diverse synthetically and naturally occurring bioactive molecules. Piperidines are an immensely important class of compounds medicinally: the piperidine ring is the most common heterocyclic subunit among FDA approved drugs.Name: 1-Methyl-4-piperidone
