Summary: By selecting a bisphosphonic ligand H4L and a coligand oxalate, three isostructural lanthanide metal-organic frameworks (Ln-MOFs) with a 2D layer structure were synthesized. By tuning the molar ratio of different lanthanide ions, doped Ln-MOFs with variable luminescent colors were obtained, which can be potentially used in anti-counterfeiting applications. Moreover, one of the Ln-MOFs (3) showed good thermal, water, and pH stabilities, and served as a selective and reusable luminescent sensor for sulfamethazine (SMZ).

Summary: We report the first complete reaction energy landscape of metal-organic framework (MOF) interpenetration, specifically in the phase transformation of NU-1200 to STA-26. The thermodynamics of this phase transformation were characterized through experiments paired with density functional theory (DFT) calculations. Time-resolved in situ X-ray diffraction and the Avrami-Erofe'ev model were used to monitor phase transformation reaction profiles and extract kinetic information. The results revealed slower phase change kinetics for MOFs with stronger bonds and a mechanistic model of partial dissolution for this phase transformation.
