  二甲基氨基甲基化单体的阴离子导电芳族共聚物：合成，性质和在碱性燃料电池中的应用。

  摘要：

  由预胺化的单体（2,5-，3,5-或2,4-二氯-N，N-二甲基苄胺）合成了一系列新型的阴离子导电芳族共聚物，并研究了其在碱性燃料电池应用中的性能。目标共聚物（QPE- bl-11a，-11b和-11c）是通过镍介导的Ullmann偶联聚合，然后进行季铵化和离子交换反应合成的。与涉及氯甲基化或溴化的常规方法不同，该方法提供具有明确化学结构的共聚物。共聚物的亲水组分由经高密度铵基改性的化学稳定的亚苯基主链组成。寡聚（亚芳基醚砜酮）用作疏水性嵌段。QPE- bl -11a通过溶液浇铸获得了坚韧且可弯曲的膜。所获得的具有最高离子交换容量值（IEC = 2.47 mequiv g –1）的膜在80°C的水中显示出高的氢氧离子导电性（130 mS cm –1）。QPE- bl-11a膜在1 M KOH水溶液中在60°C下显示1000 h时具有合理的碱稳定性。使用肼作为燃料，QPE- bl -11a作

  New protocols for controlled reduction of carboxamides to either alcohols or amines were established using a combination of sodium hydride (NaH) and zinc halides (ZnX2). Use of a different halide on ZnX2 dictates the selectivity, wherein the NaH‐ZnI2 system delivers alcohols and NaH‐ZnCl2 gives amines. Extensive mechanistic studies by experimental and theoretical approaches imply that polymeric zinc

  使用氢化钠（NaH）和卤化锌（ZnX 2）的组合，建立了将羧酰胺控制还原为醇或胺的新方案。在ZnX 2上使用不同的卤化物决定了选择性，其中NaH-ZnI 2系统提供醇，而NaH-ZnCl 2系统提供胺。通过实验和理论方法进行的广泛机理研究表明，聚合氢化锌（ZnH 2）∞负责醇的形成，而二聚氯化锌氢化物（H-Zn-Cl）2是生产胺的关键物质。

  Provided are an anion exchange resin being capable of producing an electrolyte membrane for a fuel cell, a binder for forming an electrode catalyst layer and a fuel cell electrode catalyst layer, which have an improved physical property (anion conductivity); a method for producing thereof; an electrolyte membrane for a fuel cell, a binder for forming an electrode catalyst layer and a fuel cell electrode catalyst layer produced from the anion exchange resin; and a fuel cell having the electrolyte membrane or the electrode catalyst layer. For example, the anion exchange resin is obtained by reacting a hydrophobic monomer with an aminoalkyl group-containing monomer, in which the hydrophobic monomer is composed of one aromatic ring or a plurality of aromatic rings to which two halogen atoms are bonded, and the aminoalkyl group-containing monomer is composed of one aromatic ring or a plurality of aromatic rings to which two halogen atoms are bonded and an aminoalkyl group is introduced; and by quaternizing the amino group. In the anion exchange resin, a divalent hydrophobic group formed by the residue of the hydrophobic monomer, and a divalent hydrophilic group formed by the residue of the quaternized aminoalkyl group-containing monomer are bonded via direct bond.
