We report the electrochemical synthesis of proton- and hydroxide-conducting ionomers. Sulfonated poly(phenyl ether) with various degree of functionalization was synthesized starting from a precursor isomer mixture or from pure ortho- or para-hydroxybenzenesulfonic acid. The ionic conductivity can be related to the different ion exchange capacity of the ionomers. Two hydroxide-conducting ionomers were prepared from (N-allyl-N-benzyl-N,N-dimethyl)ammonium iodide (ABDMA) or N-(p-vinylbenzyl)-N,N,N-trimethylammonium chloride (VBTMA). The ionic conductivity of VBTMA polymer is two orders of magnitude higher than that of ABDMA. This result can be explained by the different structure of the two polymers, which changes the ion mobility drastically. The electrochemical synthesis of ionomers is a promising research field, where many advances can be made by clever choice of highly functionalized precursor monomers with appropriate positions of the ionic groups.

我们报告质子和氢氧化物导电离聚物的电化学合成。从前体异构体混合物或从纯正或对羟基苯磺酸开始合成具有各种官能度的磺化聚苯醚。离子电导率可能与离聚物的不同离子交换容量有关。由（N-烯丙基-N-苄基-N，N-二甲基）碘化铵（ABDMA）或N-（对乙烯基苄基）-N，N，N制备了两种传导氢氧化物的离聚物-三甲基氯化铵（VBTMA）。VBTMA聚合物的离子电导率比ABDMA高两个数量级。可以用两种聚合物的不同结构来解释此结果，这会极大地改变离子迁移率。离聚物的电化学合成是一个有前途的研究领域，其中可以通过明智地选择具有离子基团适当位置的高度官能化的前体单体来取得许多进展。
