A reflection on ‘A hydrazone-based covalent organic framework for photocatalytic hydrogen production’: teaching sponges new tricks

, 2789-2793, https://doi.org/10.1039/C4SC00016A), and reflects on its lasting impact. We survey the major advances that have shaped COF photocatalysis over the past decade and outline emerging opportunities and challenges, offering a forward-looking perspective on the role of COFs in solar energy conversion.
