However, the low dielectric constants of organic frameworks lead to strong dielectric confinement and large exciton binding energies, which severely limit charge separation efficiency and photocatalytic performance. Herein, we report a viable strategy for modulating dielectric confinement via counteranion engineering. Halogen\u2010functionalized ionic COFs were fabricated by first synthesizing a highly conjugated EB\u2010COF:Br scaffold via Schiff base condensation between the ionic amino monomer ethidium bromide and the aldehyde linker 2,4,6\u2010triformylphloroglucinol, followed by ion exchange with F\n                    <jats:sup>\u2212<\/jats:sup>\n                    , Cl\n                    <jats:sup>\u2010,<\/jats:sup>\n                    and I\n                    <jats:sup>\u2212<\/jats:sup>\n                    .
