This work pioneers precise fluorination engineering in pyrene-based covalent organic frameworks (COFs) to unlock exceptional photocatalytic hydrogen (H 2 ) evolution. Through systematic modulation of fluorine substitution patterns, we synthesized three distinct COFs: non-fluorinated (TF 0 CN-COF), fully fluorinated (TF 1 CN-COF), and partially fluorinated (TF 0.5 CN-COF). While TF 0 CN-COF’s symmetric donor-acceptor structure permits intramolecular charge transfer, it suffers from weak electron localization and scarce active sites. Conversely,...
