Synthesis of Ether‐Free Polymer Containing Sterically Demanding Triarylsulfonium Cation in the Main Chain and Its Alkaline Stability
To develop alkaline‐ and oxidation‐tolerant polymer materials for anion exchange membranes (AEMs) in electrochemical energy conversion systems such as fuel cells and water electrolyzers, the synthesis of a polymer containing highly alkaline‐stable triarylsulfonium units is described. The Suzuki–Miyaura cross‐coupli...
