A hydrazone-based covalent organic framework for photocatalytic hydrogen production

L. Stegbauer, K. Schwinghammer, and B. V. Lotsch
Covalent organic frameworks (COFs) are a new generation of porous crystalline polymers. Drawing on the recent development of tailor-made semiconducting COFs, we here report on a new COF capable of visible-light driven hydrogen generation in the presence of Pt as proton reduction catalyst. The COF is based on hydrazone-linked functionalized triazine and phenyl building blocks and adopts a 2D layered structure with a honeycomb-type lattice featuring mesopores of 3.8 nm and the highest surface area among all hydrazone-based COFs reported to date.
