Anion conducting multiblock poly(arylene ether sulfone)s containing hydrophilic segments densely functionalized with quaternary ammonium groups
We have prepared poly(arylene ether sulfone) multiblock copolymers with cationic blocks containing single dioxyphenylene rings functionalized with two, three or four quaternary ammonium (QA) roups in order to investigate the influence of the ionic concentration and distribution on the anionic conductivity.Precursor blocks were prepared by polycondensation of 4,4’-difluorodiphenyl sulfone and eithe
