Infections caused by bacteria pose a serious threat to public health, and there is need for numerous innovative, antibiotic-free antimicrobial medicines. Herein, we describe the synthesis of CuS/Co-ferrocene-MOF (CuS/Co-Fc-MOF) nanocomposites, formed coupling CuS nanoparticles (NPs) two-dimensional (2D) Co-Fc-MOF nanosheets, that constitutes an platform capable near-infrared (NIR) photothermal promotion chemodynamic antibacterial. 2D CuS/Co-Fc-MOF nanocomposites consist nanosheets with dimensions approximately 100–200 nm thicknesses 13.1–15.6 nm, where NPs, size about 8 are excellently dispersed on surface nanosheets. The diverse valence states cobalt iron in enable them undergo Fenton-like reactions H2O2, thus generating highly oxidizing ·OH therapy (CDT). utilization local plasmonic resonance effect NPs enables enhancement CDT activity under laser irradiation. More importantly, can achieve rapid (15 min) NIR laser-assisted killing both S. aureus E. coli bacterial infection microenvironment compared Therefore, be employed as promising nanoagent promote photothermally augmented antibacterial therapy.

Delayed luminescence (DF), including phosphorescence and thermally activated delayed fluorescence (TADF), circularly polarized (CPL) exhibit common broad application prospects in optoelectronic displays, biological imaging, encryption. Thus, the combination of is attracting increasing attention. The encapsulation guest emitters various host matrices to form host-guest systems has been demonstrated be an appealing strategy further enhance and/or modulate their luminescence. Compared with conventional liquid crystals, polymers, supramolecular matrices, porous crystalline frameworks (PCFs) metal-organic (MOFs), covalent-organic (COFs), zeolites hydrogen-bonded organic (HOFs) can not only overcome shortcomings such as flexibility disorder but also achieve ordered guests long-term stability chiral structures, providing new promising platforms for development DF CPL. In this review, we provide a comprehensive critical summary recent progress photochemistry

Interlocked molecular assemblies constitute a captivating ensemble of chemical topologies, comprising two or more separate components that exhibit remarkably intricate structures. The interlocked are typically identical, and heterointerlocked systems comprise structurally distinct remain unexplored. Here, we demonstrate metal-templated synthesis can be exploited to afford not only homointerlocked cage but also cage.

Triply Interlocked [2]catenanes: Rational Synthesis, Reversible Conversion Studies and Unprecedented Application in Photothermal Responsive Elastomer

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: 63(32)

Published: May 20, 2024

Triply interlocked [2]catenane complexes featuring two identical, mechanically units are extraordinarily rare chemical compounds, whose properties and applications remain open to detailed studies. Herein, we introduce the rational design of a new ligand precursor, L1, suitable for synthesis six triply [2]catenanes by coordination-driven self-assembly. The compounds can be reversibly converted into corresponding simple triangular prism metallacage addition H
