Abstract Long‐chain alkylamines are widely used as surfactants and inevitably cause environmental pollution. However, there is still a lack of adsorbents that can efficiently remove them due to the scarcity available binding sites. Herein, this study demonstrates pore wall‐engineered polar covalent organic frameworks (COFs) with tailored size be promising nanotraps for rapid highly efficient capture octadecylamine (ODA, typical long‐chain alkylamine) from complex practical samples (e.g., salt lake brine). Under optimized conditions, nitro‐functionalized COFs (TpPa‐NO 2 TpBD‐NO ) show much better ODA adsorption performances than unfunctionalized TpPa, TpPa‐NO , whose matches molecule best, obtained an capacity high 128.5 mg g −1 within 20 min. Density functional theory (DFT) calculations molecular dynamics (MD) simulations elucidate underlying mechanisms, revealing provide multiple interaction forces, including electrostatic, polar, van der Waals, hydrogen bond, hydrophobic, C─H σ–π interactions, which synergistically contribute in 1D . This provides theoretical foundation experimental evidence utilizing alkylamine offers strategy designing functionally applications.
