Summary: A novel series of heterometallic f-block-frameworks, including the first examples of transuranic heterometallic U-238/Pu-239-MOFs, and a novel monometallic Pu-239-analog, were reported. The kinetics and thermodynamics of heterometallic actinide-MOF formation were probed, with the first value of a U-to-Th transmetallation rate reported. Density of states, enthalpy of formation, band gap, proton affinity, and thermal/chemical stability were investigated as a function of metal ratios.

Summary: Acquiring fundamental knowledge of properties of actinide-based materials is crucial for addressing challenges in nuclear energy and waste sectors. In this study, a correlation between photophysics and electronics in actinide-containing metal-organic frameworks was established for the first time, allowing for dynamic modulation of electronic properties. The construction of a photochromic MOF-based field-effect transistor demonstrated the potential for light-induced changes in current, enabling the operation of a fail-safe indicator circuit.

Summary: Bond breaking is a new tool for postsynthetically modifying the pore structure in metal-organic frameworks. In this study, the concept of clip-off chemistry is extended to ZIF-8, and the different stabilities of bonds between imidazolate and Zn and Fe metal atoms in heterometallic Fe-Zn-ZIF-8 are utilized. It is demonstrated that Fe centers can be selectively removed without affecting the backbone structure supported by Zn atoms. This strategy allows for the creation of mesopores within the highly stable ZIF-8 structure and opens up new possibilities for designing novel hierarchical porous frameworks.

Summary: Two heterometallic metal organic frameworks, MOF2 and MOF3, were synthesized by two-step strategies. These frameworks exhibited different topological structures and contained FeII and FeIII ions in a 1:1 ratio. Additionally, the transformation process involved dissolution, self-reduction of FeIII to FeII, and the cleavage/regeneration of coordination bonds, with heterogeneous catalytic effects observed in the synthesis of imines under solvent-free conditions.

Summary: The formation of hierarchical porosity in HP HKUST-1 MOFs was investigated using gemini surfactants as soft-templates. The composition of solvent mixtures and reaction parameters played a crucial role in the successful formation of hierarchical porosity. The presence of mesopores in the samples was proven through various characterization techniques, and a direct correlation was found between the hierarchy factor and dye-uptake, suggesting the potential of the hierarchy factor as a quantitative marker for hierarchical porosity.

Summary: In this study, we demonstrated the construction of a composite system with turn-on mechanofluorochromism by incorporating aggregation-induced emission (AIE) materials within metal-organic framework (MOF) single crystals. The unique fluorochromism mainly originated from the enhanced nanoconfinement effect exerted by the MOF host on the AIE guest under pressure. This innovative design strategy offers new possibilities for the fabrication of efficient mechanofluorochromic materials.

Summary: This study directly investigates local defects in ZIF-8 nano- and microcrystals using near-field IR nanospectroscopy and density functional theory calculations. The research shows that some structural defects gradually disappear during crystallization, while dangling and missing linker defects persist. These structural defects reduce the Young's modulus of the crystals but also offer opportunities for defect engineering to tune the performance of ZIF-8 by providing additional adsorption sites.

Summary: Luminescent metal-organic frameworks (LMOFs) are promising for nanophotonic applications, but their 3D nature presents challenges. Metal-organic nanosheets (MONs) overcome these limitations by combining MOFs with an atomically thin morphology. This study reports the synthesis of thin ZIF-7-III MONs through low-energy salt-templating, which show intense and highly photostable fluorescence when intercalated with fluorophores. Aggregation and Forster resonance energy transfer are revealed as the mechanisms for fluorescence, providing quantified control over emission chromaticity.

Summary: This study reports the synthesis of polyureas through the dehydrogenative coupling of diamines and diformamides. The reaction is catalysed by a manganese pincer complex and produces H-2 gas as the only by-product, making the process atom-economic and sustainable. Compared to the current production routes using diisocyanate and phosgene feedstock, this method is greener. The physical, morphological, and mechanical properties of the synthesized polyureas are also investigated. Based on mechanistic studies, the reaction is proposed to proceed via isocyanate intermediates formed by the manganese-catalysed dehydrogenation of formamides.
