N-Spirocyclic cations have excellent alkali resistance stability, and precise design of the structure N-spirocyclic anion-exchange membranes (AEMs) improves their comprehensive performance. Here, we synthesize high-performance poly(triphenylene piperidine) based on "fishbone" amino/N-spirocyclic cations. The does not disrupt overall stabilized conformation but promotes a microphase separation structure, while exerting synergistic effect piperidine spirocyclic cations, resulting in membrane with good conductivity stability. hydroxide QPTPip-ASU-X reached up to 133.5 mS cm–1 at 80 °C. QPTPip-ASU-15 was immersed 2 M NaOH solution °C for 1200 h, maintained 91.02%. In addition, QPTPip-ASU-5 had highest peak power density 255 mW cm–2.
