Abstract : Cyclopropenium cations with differing amino-functional groups were synthesized and tested for their utility in anion exchange membranes for alkaline fuel cells. A series of aminocyclopropeniums were synthesized and their base stability probed in situ using time-resolved proton nuclear magnetic resonance (1H NMR) under conditions designed to mimic those encountered in alkaline fuel cells to test their utility in anion exchange membranes. While the aminocyclopropeniums showed poor base stability, the cyclopropenium cation may have beneficial properties in neutral pH applications such as antimicrobial fabrics and coatings.
