Summary: The study demonstrates that the use of highly spatioselective photochemistry can increase the structural complexity of MOF-based architectures, leading to the delamination of top layers and the formation of two-dimensional MOF sheets with defined thickness. This opens up new possibilities for fabricating planar MOF structures using photolithography.

Summary: Developing a nanotheranostic with high sensing performance and efficient therapy is significant for cancer diagnosis and treatment. In this study, a nanotheranostic was constructed using Au nanoparticles and hairpin-loaded photosensitive metal-organic framework (PMOF@AuNP/hairpin). The nanotheranostic not only facilitated efficient PDT through the conversion of O-2 into ROS, but also showed catalase-like activity to generate O-2 from H2O2, enhancing the antitumor effect of PDT. Additionally, it demonstrated high loading efficiency of hairpins and sensitive detection of miR-21 in living cells and in vivo, as well as dynamic monitoring of miR-21 level.

Summary: A novel aminal-linked porphyrinic COF, Por-Aminal-COF, was synthesized and characterized. It exhibited excellent photocatalytic activity for the detoxification of sulfur mustard simulant with a much shorter half-life compared to the traditional imine-linked Por-COF. The superior photocatalytic performance of Por-Aminal-COF was attributed to its aminal linkages, which facilitated the intersystem crossing process and enhanced triplet-state generation efficiency.

Summary: This study presents a new covalent organic framework (COF) named PyPor-COF, which is a highly efficient photosensitizer. The COF combines photoactive porphyrin moieties through in situ-formed imidazole groups and exhibits high crystallinity, permanent porosity, robust stability, and semiconductive photo response activity. It can effectively initiate the generation of singlet oxygen (1O2) under visible-light irradiation, surpassing the efficiency of other porphyrin-based reactants and commercially available photosensitizing agents. The COF also shows potential in triggering 1O2 production in a physiological environment, making it a promising candidate for photodynamic therapy.

Summary: Metal-organic frameworks with well-organized low-dimensional architectures provide significant thermodynamic and/or kinetic benefits for diverse applications. This study focuses on the controlled synthesis of a novel class of hierarchical zirconium-porphyrin frameworks (ZrPHPs) with nanosheet-assembled hexagonal prism morphology. The ZrPHPs exhibit an assembly-hydrolysis-reassembly mechanism towards the formation of 2D nanosheets with ordered arrangement. Due to their highly-accessible active sites, ZrPHPs serve as adaptable photocatalysts for macromolecular synthesis under full-range visible light and natural sunlight.

Summary: The conversion of wetlands to aquaculture ponds alters phosphorus (P) cycling and its budget balance, leading to increased P release into water and exacerbating water quality degradation and eutrophication in coastal areas. This study investigates the availability and mobilization mechanisms of P in natural coastal wetlands and converted aquaculture ponds using advanced techniques, revealing that the conversion weakens the dependence of sediment P mobilization on iron and sulfur reactions. The findings emphasize the urgent need for specific actions to alleviate internal P-loading in aquaculture.

Summary: Since the initial assessment four decades ago, research on the hydrogen-storage applications of zirconium diberyllide, ZrBe2, has mainly focused on its hydride composition, ZrBe2H1.5. However, recent studies using neutron techniques have revealed the existence of two other ordered phases of ZrBe2Hx with lower hydrogen contents (x < 1.5) at low temperatures. These phases have different structural symmetries, H-sublattice orderings, and undergo higher-temperature phase transitions. This study provides a more complete understanding of the ZrBe2Hx phase diagram.

Summary: This study investigates the thermal polymorphism in CsCB11H12 and discovers the existence of two polymorphs: the ordered R3 polymorph at around 313K and the disordered I43d polymorph at around 353K. Additionally, it identifies a disordered Fm3 polymorph appearing from the disordered I43d polymorph at 513K and transforming into a high-temperature P6(3)mc polymorph. Neutron scattering results show isotropic rotational diffusion of CB11H12- anions in the disordered phase at 560K.

Summary: By incorporating structure-directing agents (SDAs) into the hydrogen-bonding network of TCPP, a series of HOFs with different pore structures were obtained. Among them, HOF-ZSTU-2 forms a strong layered hydrogen-bonding network with ammonium (NH4+) through multiple carboxyl groups and has a suitable 1D pearl-chain channel for the selective capture of propylene (C3H6). HOF-ZSTU-2 achieves a C3H6 storage density of 0.6 kg L-1 at 298 K and 1 bar, and exhibits a propylene/propane (C3H6/C3H8) selectivity of 12.2.

Summary: The tumor microenvironment has low pH, high ROS levels, and hypoxia, which facilitate cancer growth. Hypoxia not only promotes tumor angiogenesis and metastasis, but also leads to treatment resistance, which hinders cancer therapy. In this study, a biomimetic nanosystem containing red blood cell-derived hemoglobin, chemotherapy drug sorafenib, sensitizer ursolic acid, and photosensitizer indocyanine green was developed for enhanced chemo-phototherapy of hepatocellular carcinoma. The nanosystem improves chemotherapy efficacy through synergistic effects of ursolic acid and achieves phototherapy using indocyanine green. Additionally, hemoglobin facilitates oxygen delivery to the tumor site and ameliorates the hypoxic environment. This dual-sensitization drug delivery system shows promise in overcoming treatment resistance caused by tumor hypoxia in hepatocellular carcinoma.

Summary: Building robust porous molecular architectures through van der Waals interactions is promising for catalysis, chemosensing, and separation techniques. This study presents a molecular porous crystal with layered packing and interdigitation of concaved building blocks. Despite the interdigitation, one-dimensional channels emerge due to the irregular shape and size of the constituent building blocks, showing significant structural flexibility and exceptional thermal and chemical stability.
