Post-synthetic linker installation in a single-crystal-to-single-crystal manner was crystallographically demonstrated in thorium-based metal-organic frameworks (Th-MOFs), not only leading to the discovery of an extremely rare framework de-interpenetration, but also representing an unprecedented strategy for boosting iodine adsorption capacity.

Metal-organic frameworks (MOFs) are hybrid inorganic-organic 3D coordination polymers with metal sites and organic linkers, which are a "hot" topic in the research of sorption, separations, catalysis, sensing, and environmental remediation. In this study, we explore the molecular mechanism and kinetics of interaction of the new copper porphyrin aluminum metal-organic framework (actAl-MOF-TCPPCu) compound with a vapor of the volatile organic sulfur compound (VOSC) diethyl sulfide (DES). First, compound was synthesized by post-synthetic modification (PSM) of Al-MOF-TCPPH compound by inserting Cu ions into the porphyrin ring and characterized by complementary qualitative and quantitative chemical, structural, and spectroscopic analysis.

The pressing demand for critical metals necessitates the development of advanced ion separation technologies for circular resource economies. To separate transition metal ions, which exhibit near-identical chemical properties, adsorbents and membranes must be designed with ultraselective chemistries. We leverage the customizability of metal-organic frameworks (MOFs) to systematically study the role of material chemistry in sorption and selectivity of Co, Ni, and Cu.

Reticular chemistry has in the post-synthetic modification (PSM) of frameworks one of the most versatile tools to adapt the systems' physicochemical properties to the specific requirements which are imposed by their application in different contexts. We can safely say that PSM methodologies in all their variants are currently one of the main resources that reticular chemists turn to when they need to diversify a framework compositionally. Practically all these modifications require the integration of functional groups appended to the organic linkers in the framework, either by direct synthesis or by post-synthetic exchange.

Metal-organic frameworks (MOFs) with a Zr-oxo cluster [(ZrO(OH))] are exceptionally stable and offer vast potential for a wide range of applications. Synthesis parameters strongly affect the quality, stability, morphology, , of the MOFs. In this study, we present an experimental set-up that allows following element-specific chemical transformations during synthesis and the effect of various reaction parameters on the reaction products.
