Novel Aromatic Sulfonic Ester Derivatives, Polyarylene, Polyarylene Having Sulfonic Acid Group and Process for Preparing the Same, and Polymer Solid Electrolyte and Proton-Conductive Membrane

摘要

The present invention is suitably used in the polyarylene, the method safe and having polyarylene of the manufacturing method and the sulfonic acid group having a sulfonic acid group which can easily control the introduced amount, the introduction position of sulfonic groups to the polymer polyarylene, and to provide an aromatic sulfonic acid ester derivative represented by the general formula (1). In addition, the present invention provides a polymer solid electrolyte, the proton conductive containing polyarylene having the sulfonic acid. ; method for producing polyarylene having a sulfonic acid group is alkylene and an aromatic compound containing at least a derivative of the general formula (I) coupling polymerization, parts of the obtained polyarylene singer. Of ; formula, X is a halogen atom except fluorine, -OSO ₃ CH ₃ or -OSO ₃ CF ₃ , A, B is a divalent organic group, R ^a is a hydrocarbon group of a carbon number of 4 to 20, Ar is a substituent -SO ₃ R ^b (wherein, R ^b is having 4 to 20 hydrocarbon group of a) an aromatic group having a, m, n are 0 to 10, m + n is 1 , k is 1 to 4.
