Summary: In this study, new solvent-responsive two-dimensional metal-organic frameworks were reported, and their transformation from 2D to 3D was induced by solvent and ligand-substitution reactions. Photodegradation experiments showed that one of the materials exhibited higher photocatalytic activity. First-principles computations suggested that this high activity could be attributed to the suitable band-edge position for redox reactions.

Summary: The sensing and monitoring of toxic oxo-anion contaminants in water are important to biological and environmental systems. A hydro-stable SIFSIX metal-organic framework, SiF6@MOF-1, with exchangeable SiF62- anion in its pore is designed and synthesized for selective detection of toxic Cr2O72- oxo-anion in an aqueous medium. The mechanism behind the selective detection is revealed through single-crystal-to-single crystal fashion and density functional theory calculations.

Summary: This study presents a lanthanide-based metal-organic framework (MOF) that emits near-infrared (NIR) light with Yb3+ sensitized by fluorescein (FL) as a low energy absorbing chromophore (FL@CD-MOF-161). The unique design of CD-MOF-161 allows for efficient loading and spreading of chromophores within the crystal volume, achieved by trapping FL molecules in its pores during synthesis and crystal growth.

Summary: In this paper, amorphous ZIF-8 was modified with carboxyl functional groups (H3BTC-ZIF-8) to load organic fluorescent dyes (R6G and C151) and prepare R6G/C151/H3BTC-ZIF-8 composite films. The enhanced fluorescence properties were attributed to the increased interactions between the dyes and H3BTC-ZIF-8, which reduced the ACQ effect and resulted in a white-light-emitting composite film with high photoluminescence quantum yield (PLQY). This strategy provides guidance for the development of white-light-emissive materials.

Summary: Transition metal-catalyzed divergent synthesis through alternation of the catalyst is demonstrated, providing an operationally simple way to access different valuable products from the same reactants. A gold-catalyzed cascade reaction of conjugated diynamides with allylic alcohols is described, giving selectively substituted allenes and furans by varying the catalysts. Mechanistic studies reveal a [3,3]-sigmatropic rearrangement and an intramolecular Himbert arene/allene Diels-Alder cycloaddition as additional reaction sequences to access dearomatized products with bicyclo[2,2,2]octadiene core.

Summary: This study reports 2D lead-MOFs that generate white light through the combined effect of free excitons and self-trapped excitons. The synthesized BIF-142-Cl exhibits outstanding white-light emission with color coordinates close to pure white light, excellent color rendering index, and gentle correlation color temperature. Additionally, the emission can be adjusted from blue to white light by changing the excitation wavelength. This synthetic strategy not only offers potential for solid-state lighting materials but also expands possibilities in anticounterfeiting, display media, and information identification fields.

Summary: In this study, a racemic compound hexanuclear silver cluster (Ag-6-Rac) protected by non-chiral ligands is reported, which can undergo chiral resolution and form a racemic conglomerate (Ag-6-S/Ag-6-R) through solvent-induced crystallization. Interestingly, the Ag-6-Rac clusters exhibit strong luminescence in solid and solution, and can respond to trifluoroacetic acid (TFA) and undergo reversible cycling using diethylamine (DEA). This work provides a new research model for resolving racemic clusters and constructing stimulus-responsive clusters.

Summary: By incorporating Ti4L6 (L = embionate) cages and various N,N-chelated transition-metal cations with strong inherent pi-conjugation properties, tight-packed high-performance materials with adjustable nonlinear optical (NLO) effects are achieved. These cage-based ionic pairs exhibit different supramolecular packing structures, including a pi-midline ellipsis pi stacked porous framework with strategically located Ti4L6 cages. Introduction of large pi-conjugated 1,10-phenanthroline type ligands with adjusted aromatic ring electron cloud density effectively regulates their third-order NLO properties, resulting in nonlinear absorption responses from reverse saturated absorption (RSA) to saturated absorption (SA). This work not only presents an extraordinary coordination cage-based assembly, but also provides new insights into the function of cage materials.
