To overcome the intrinsic processability limitations of hydrogen\u2010bonded assemblies, we develop an interfacial chemical reaction\u2010mediated confined assembly strategy that suppresses stochastic nucleation and yields continuous, defect\u2010minimized crystalline HOF membranes. This isoreticular platform preserves identical channel geometry while enabling systematic modulation of pore\u2010wall nitrogen density as an independent chemical variable, effectively decoupling structural confinement from chemical regulation. Multiscale simulations and temperature\u2010dependent transport measurements reveal that nitrogen enrichment selectively amplifies the translocation energy barrier for Sr\n                    <jats:sup>2+<\/jats:sup>\n                    while maintaining low\u2010barrier hopping pathways for Cs\n                    <jats:sup>+<\/jats:sup>\n                    .
