Abstract Polyamidoxime (PAO) and its derivatives are widely regarded as promising adsorbents for uranium extraction from seawater. However, their close‐packed structure encapsulates a large number of adsorption sites slows down the transfer rate uranyl ions, resulting in slight capacity. Herein, PAO polymer chains synthesized through molecular coordination template method carboxylate covalent organic framework (COF) to obtain PAO‐inserted COF adsorbent with open ion transport channels. After removing protons, COO − groups form situ electric fields inside 0.7 nm channel. This negatively‐charged reduces electrostatic repulsion among cations, thus realizing ultrahigh utilization (81.0%), far exceeding that classical amidoxime‐based (33.7%). 10 days contact natural seawater, COF‐PAO achieved an average capacity ≈12.26 mg‐U per g Bohai (China), satisfying standard (6.0 mg −1 ). work enumerates control spatial environment chains, provides guidance design subsequent high‐efficiency adsorbents.
