Interlayer-stacking mode modulation in an imine covalent organic framework for efficient photocatalytic hydrogen production

An AB-stacking COF outperforms its AA-stacking isomer as a photocatalyst for hydrogen production, with the HER increasing from 46.8 to 109.6 mmol g −1 h −1 . AB-stacking outperforming AA-stacking is a rare and notable example in the COF field.
