Abstract Charged covalent organic framework (COF) membranes have gained wide interest as the key component in reverse electrodialysis technique to harness salinity energy. However, maintaining rapid ion transport and high selectivity a Ca 2+ ‐rich environment remains formidable challenge. Herein, highly cation‐conductive azine COF membrane is synthesized via layer‐by‐layer chemical reaction between 2,4‐dihydroxy‐1,3,5‐diphenyltrialdehyde (DHTA) hydrazine hydrate (HZ). The osmotic energy generator based on this delivers power density of 17.8 W m −2 under 2.5 M/0.05 M CaCl 2 , outperforming TFP‐HZ (3.2 ), commercial benchmark (5 other literature reported owing simultaneous modulation charges angstrom scale channels selective layer thickness. Moreover, comparable that NaCl gradient (2.5 M, 16.9 which rare. These results indicate DHTA‐HZ suitable for application hypersaline environments containing serving an inspiration development COF‐based nanofluidic with output efficiency practical high‐salinity environment.
