The structural transformation of metal–organic frameworks (MOFs) has attracted increasing interests, which not only produced various new structures but also served as a fantastic platform for MOF-based kinetic analysis. Multiple reaction conditions have been documented to cause transformation; nevertheless, central metal-induced topological alteration MOFs is rare. Herein, we reported 2D layered Cd-MOF driven by Cd(II) ions. After being submerged in the aqueous solution cadmium nitrate, twofold interpenetrated network [Cd(hsb-2)(bdc)·5H2O]n [HSB-W10; bdc: 1,4-benzenedicarboxylate; hsb-2:1,2-bis(4′-pyridylmethylamino)-ethane] was converted into novel noninterpenetrated [Cd1.5(hsb-2)(bdc)1.5(H2O)2·H2O]n (HSB-W16). This partial dissolution–recrystallization process investigated integrating controlled experiments, 1H NMR spectra, and photographic tracking Furthermore, strategy combining situ multicomponent dye encapsulation metal-triggered developed fabrication MOF materials with white-light emission. By adopting this strategy, different guest molecules were concurrently introduced HSB-W16 host matrix, leading range white-light-emitting composites. work will enable detailed studies solid-state transformations demonstrate promising application prospect transformation.
