In this review the research of the author's group regarding the optimization of the chemical stability and properties of aromatic ion-exchange polymers by suitable and systematic synthesis of electron-deficient monomer building blocks and by their (co) polymerization into highly stable aromatic ionomers are presented. Moreover, the preparation of physically or covalently cross-linked ion-exchange membranes by blending these ionomers with each other and with suitable commercial polymers to finally afford ion-exchange membranes with properties tailored for electromembrane applications such as fuel cells, electrolyses, and redox-flow batteries are described
