While microporous architectures can facilitate ion transport, the accompanying structural disorder often compromises membrane stability. In this study, we introduce a topology\u2010regulated packing strategy by incorporating triphenylene (TP) units into the polymer backbone to manipulate intermolecular organization. Molecular simulations and structural characterizations reveal that the TP topology induces dual stacking configurations, consisting of compact and tilted packing motifs. The coexistence of these two stacking modes enables the formation of ordered domains while preserving interconnected free volume, thereby promoting continuous ion\u2010transport pathways without excessive swelling. As a result, the optimized membrane exhibits a hydroxide conductivity of 178.39 mS cm\n                    <jats:sup>\u22121<\/jats:sup>\n                    with a low swelling ratio of approximately 10% at 80\u00b0C. Diffusion analyses further suggest that the topology\u2010induced packing structure creates a favorable hydrated environment and facilitates efficient hydroxide transport. In AEMWE operation, the membrane delivers a current density of 3.163 A cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    at 1.8\u2009V and 80\u00b0C and maintains stable operation for over 4000 h at 1 A cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    .
