However, the selective removal of bromide from reverse osmosis (RO) permeate remains challenging. Herein, we report a benzothiazole\u2010functionalized covalent organic framework (COF) designed as a chalcogen\u2010bond donor, where \u03c3\u2010holes along the C\u2500S bond axes preferentially interact with the softer, more polarizable Br\n                    <jats:sup>\u2212<\/jats:sup>\n                    over Cl\n                    <jats:sup>\u2212<\/jats:sup>\n                    . Two COFs, mesoporous BTzTp (\u223c2.45\u00a0nm) and microporous TTzTp (\u223c1.13\u00a0nm), were investigated to assess the role of pore accessibility while preserving identical recognition sites. The BTzTp@rGO composite exhibited a specific capacitance of 47 F g\n                    <jats:sup>\u2212<\/jats:sup>\n                    <jats:sup>1<\/jats:sup>\n                    and a maximum bromide adsorption capacity of 36.7\u00a0mg\u2010Br\n                    <jats:sup>\u2212<\/jats:sup>\n                    g\n                    <jats:sup>\u2212<\/jats:sup>\n                    <jats:sup>1<\/jats:sup>\n                    at pH 4. Notably, it maintained \u223c99% capacitance retention after 50 cycles, representing the highest cycling stability reported for a bromide\u2010selective HCDI electrode, together with excellent selectivity (\u03b1\n                    <jats:sub>Br\/Cl<\/jats:sub>\n                    = 10). Density functional theory calculations reveal that selectivity originates from strong chalcogen bonding, evidenced by near\u2010linear C\u2500S\u00b7\u00b7\u00b7Br\n                    <jats:sup>\u2212<\/jats:sup>\n                    geometries (178\u00b0\u2013179\u00b0), normalized contacts of 0.84, HOMO delocalization across the S\u00b7\u00b7\u00b7Br\n                    <jats:sup>\u2212<\/jats:sup>\n                    interface, and greater charge transfer to Br\n                    <jats:sup>\u2212<\/jats:sup>\n                    (0.222 e) than Cl\n                    <jats:sup>\u2212<\/jats:sup>\n                    (0.154 e).
