Employing a two‐dimensional covalent organic framework as the reusable solar photosensitizer, the sunlight‐driven aerobic oxidative construction of a nitrogen‐sulfur bond has been achieved. 3,5‐Disubstituted 1,2,4‐thiadiazoles are smoothly prepared in water by using this procedure. Furthermore, a radical mechanism with a sunlight‐promoted single electron transfer (SET) process is proposed for this transformation.
