Comprehensive Summary The visible light‐driven photoswitches are attracting widespread attention, but it is challenging to leverage their phototriggered structural changes regulate dynamic bonds, assemblies, and materials. Herein, we incorporated reversible covalent sites of aldehyde ring‐chain tautomers into all‐visible‐light azobenzenes toward a versatile platform for light‐controlled formation/exchange C—N bonds from secondary amines. movement equilibrium was attained via manipulating intramolecular multiple hydrogen bonding E / Z configurational isomers. Such regulation further enabled photocontrolled kinetics the formation exchange reactions cyclic hemiaminal ethers amines exhibiting kinetic rate reversal varied capability isomers in engaging azo attached carboxylate with ammonium salt accounts difference. Moreover, photoswitching performance different solutions readily regulated by reactivity control light associated mechanistic foundation add collection photoswitchable chemistry would lay subsequent biological material applications.
