Abstract Utilizing aggregation‐induced emission luminogens (AIEgens) as ligands has proven to be an effective strategy for constructing metal–organic frameworks (MOFs) with intense luminescent properties. However, highly AIEgen‐based MOFs adjustable properties are rarely achieved because of the rigid conformation AIEgens in crystalline state. Here, a dual‐node 3D silver chalcogenolate cluster MOF ( 1 ) is designed and synthesized, where AIE ligand shows relatively flexible rotatable conformations. The conformations switchable by absorption/desorption guest molecules. As result, exhibited not only but also molecule switched More importantly, switching rate tunable using different provides unique visualized prototype understand mechanism guest‐triggered MOFs.
