Summary: A hydroxyl-functionalized 3D covalent organic framework (TAPM-DHBD) with strong fluorescence and 3D interconnected pore channels was synthesized and evaluated for uranium detection and extraction. TAPM-DHBD exhibited exceptional uranium extraction capacity and fast kinetics, with an ultra-low detection limit suitable for sensitive and on-site monitoring of radioactive uranium contamination. Furthermore, TAPM-DHBD showed excellent regenerable performance, providing a new strategy for radioactive contamination monitoring and strategic nuclides extraction.

Summary: The self-assembly of Zn(NO3)2 center dot 6H2O, benzene-p-dicarboxylic acid (H2BDC) and tris(4-(4H-1,2,4-triazol-4-yl) phenyl)amine (L) provides a new Zn(II)-based metal-organic framework (MOF) with the formula {[Zn3(L)(BDC)3(H2O)3]center dot 3.5H2O}n (1). The structural analysis reveals that complex 1 exhibits an 8-fold interpenetrated three-dimensional network with a 3-connected srs net. Photoluminescent study shows that the strong emission of 1 at room temperature is attributed to interligand-based charge-transfer.

Summary: Luminescent metal-organic frameworks are alternative sensors that offer selective and sensitive detection of chemical species such as benzaldehyde. The interactions between benzaldehyde and the metal-organic framework result in luminescence quenching, which is attributed to an electron-transfer process. This study provides insights into the detection mechanism and properties of benzaldehyde using a zinc-based LMOF.

Summary: This study investigates the regulation mechanism of AuNCs-based AIEE system by studying the Zn2+-induced AIEE process of thiolate ligands protected AuNCs. The pH-dependent evolution from single AuNCs to spheric aggregates to irregular network is observed. The concept of mid-pH is proposed to indicate the optimal pH for the formation of spheric AuNCs aggregates. The spheric AuNCs aggregates, with tunable mid-pH between 5.7 and 7.5, show targeted tumor cell uptake and imaging at physiological pH mainly through clathrin-mediated endocytosis.

Summary: This study successfully loaded the air-sensitive cationic molecule magnesocene (MgCp2) into the three-dimensional pores of NH2-MIL-101(Al) using a gas-phase infiltration process, demonstrating a maximum loading of 43.1 wt %. It was also observed that MgCp2 covered the outside of Ni-MOF-74 due to its small one-dimensional channels.

Summary: CCIQS-1 is a new guest-responsive flexible MOF that exhibits permanent porosity but undergoes a crystal-to-crystal phase transition upon solvent removal, leading to the contraction of hydrophobic pores while hydrophilic channels remain open. The material shows higher affinity for adsorbates with moderate polarity and triggers the recovery of open-pore phase through a combination of breathing effect and subnetwork displacement.

Summary: In this study, MnCo2S4 nanosheet catalyst was successfully synthesized and found to exhibit superior performance in hydrogen evolution. Compared to MnCo2S4, MnCo2S4 showed low overpotentials, moderate Tafel slope, and excellent sustainability. The outstanding performance can be attributed to the increased number of electrochemically active sites and enhanced electronic conductivity on the catalyst surface.

Summary: Networks are important for describing relationships between people, roads between cities, reactions between chemicals, and other interactions. Bipartiteness, dividing the network into two groups, can facilitate the study of the network's structure. We have developed an algorithm that can find a near-optimal bipartisation within a reasonable time frame and used it to uncover the hidden structure of the CSD cocrystal network.
