摘要
Covalent organic frameworks(COFs)characterized by structural diversity,face-to-face stacking and open channels exhibit unique advantages as photothermal materials but have rarely been applied in solar-driven water evaporation due to complicated framework design,tedious synthesis,and low solar-to-vapor efficiency.Herein,we report a materials design strategy to produce efficient and robust photothermal COF by anchoring nonemissive radicals to the pore surface by a[2+2]cycloaddition–retroelectrocyclization reaction.
