Partially fluorinated and ammonium‐functionalized terpolymers: Effect of aliphatic groups on the properties of anion conductive membranes 下载免费PDF全文
Hideaki Ono Junpei Miyake Kenji Miyatake 《Journal of polymer science. Part A, Polymer chemistry》2017,55(8):1442-1450
Synthesis and properties of a series of ammonium‐containing terpolymers (QPAF‐3) as anion conductive membranes are reported. The QPAF‐3s composed of perfluoroalkylene, alkylene, and ammonium‐functionalized phenylene groups without heteroatom linkages in the main chain were synthesized via nickel‐mediated polycondensation reaction, followed by chloromethylation, quaternization, and ion exchange reactions. Self‐standing, bendable membranes were obtained by solution casting. The QPAF‐3 membrane with optimized terpolymer composition and ion exchange capacity (1.46 meq g?1) showed high hydroxide ion conductivity (123 mS cm?1 in water at 80 °C). The alkaline stability test in 1 M KOH for 1000 h at 80 °C and the post‐test analysis with IR spectra and tensile strength suggested that ammonium groups were likely to be decomposed while the polymer main chain was chemically more robust. The presence of the alkylene groups in the terpolymers lowered solubility, glass transition temperature, and elongation property of the resulting membranes. © 2016 Wiley Periodicals, Inc. J. Polym.

The 4‐quinolone‐2‐carboxylates 4a,b were converted into the 4‐quinolone‐2‐carbohydrazides 5a,b , hydrazones 6,7,10 , and related compounds 8,9,11 . The 4‐methoxyquinoline‐2‐carboxylate 12 was also transformed into the 4‐methoxyquinoline‐2‐carbohydrazide 13 , which was modified to the hydrazone 14 and related compound 15 . The antimicrobial activities of compounds 6b and 14 are described together with the 4‐oxo and 4‐hydroxy tautomers of compounds 4‐11 in deuteriodimethyl sulfoxide and deuteriotrifluoroacetic acid. 相似文献
