Liquid–liquid interfacial approach for the facile synthesis of Tp–NBD COFs for efficient photocatalytic hydrogen production

A β-ketoenamine-linked 2D COF with a non-planar amine monomer is reported for photocatalytic H 2 evolution. It exhibits a high surface area (677.5 m 2 g −1 ) and HER activity of 21 mmol g −1 h −1 , demonstrating excellent efficiency and stability.
