A halogenated aromatic compound, a polyarylene (co)polymer obtained by thenpolymerization of such a halogenated aromatic compound as a monomer component,nand a proton-conductive membrane made of a sulfonation product of such a (co)polymernare disclosed. The halogenated aromatic compound is represented by the followingngeneral formula (1bm):n nwherein As' independently represent an electron-withdrawing group; Bs' independentlynrepresent an electron-donating atom or divalent group; Xs' independently represent anchlorine atom, an iodine atom, or a bromine atom; Z represents an aryl group; R 1 to R 19 nmay be the same or different and each represents a hydrogen atom, a fluorine atom, annalkyl group, or a fluoroalkyl group; and a and b each represents an integer of 1 to 20. |
