A robust 2,2′‐bipyridine (bpy)‐derived biological hydrogen‐bonded framework (HOF‐25) has been realized depending on guanine‐quadruplex with the assistance of π‐π interaction, which reacts with Re(CO) 5 Cl to give a post‐functionalized HOF‐25‐Re. X‐ray absorption fine structure spectroscopic study on HOF‐25‐Re confirms the covalent attachment of Re(bpy)(CO) 3 Cl segments to this HOF. Robust and recycled HOF‐25‐Re bearing photocatalytic Re(bpy)(CO) 3 Cl centers displays good heterogeneous catalytic activity towards carbon dioxide photoreduction in the presence of [Ru(bpy) 3 ]Cl 2 and triisopropanolamine in CH 3 CN under visible‐light irradiation, with both high CO production rate of 1448 μmol g −1 h −1 and high selectivity of 93 %. Under the same conditions, the experimental turnover number of HOF‐25‐Re (50) is about 8 times as that of the homogeneous control Re(bpy)(CO) 3 Cl. The sustainably regenerated HOF‐25‐Re via crystallization and post‐modification processes shows recovered photocatalytic performance.
