Here we present a green, external\u2010acid\u2010free route to fabricate defect\u2010free covalent organic framework (COF)\u2010based thin\u2010film composite (TFC) membranes for high precision monovalent\u2010ion sieving. The method relies on a dynamic electric\u2010field\u2010assisted strategy in which an alternating electric field couples electrophoretic monomer assembly at the surface of an ion\u2010exchange membrane (IEM) substrate with spatiotemporally resolved delivery of hydronium ions generated in situ via water splitting. This localized in situ\u2010generated acid pulse initiates interfacial condensation into primary COF nuclei, which subsequently undergo continuous growth and fusion into a uniform ultrathin film through a self\u2010healing mechanism. The proposed membrane formation strategy effectively suppresses non\u2010selective transport pathways and enables rapid formation of highly selective ion\u2010transport channels, resulting in a membrane with near\u2010complete fractionation of Li\n                    <jats:sup>+<\/jats:sup>\n                    from other monovalent ions (e.g., K\n                    <jats:sup>+<\/jats:sup>\n                    and Na\n                    <jats:sup>+<\/jats:sup>\n                    ), while preserving fast ion permeation that exceeds that of previously reported membranes. The governing ion separation mechanism is elucidated as hydration\u2010shell restructuring under electrostatic confinement. The work establishes a scalable and energy\u2010efficient platform for precision ion separation and opens new opportunities for membrane\u2010based resource recovery and molecular purification.\n
