“…Metal–organic frameworks (MOFs) are a class of porous ordered framework material that have been widely applied in various fields due to their remarkable physical and chemical properties, including high porosity, the possession of multiple active sites, high specific surface area, tunable morphology, and excellent biodegradability. 31–53 Recently, some porphyrin-based sonosensitizers ( e.g. , HMME: hematoporphyrin monomethyl ether, and TCPP: tetrakis(4-carboxyphenyl)porphyrin) have been used as organic ligands to assemble MOFs with various metal ions ( e.g.…”

“…Due to the minimal likelihood of developing drug resistance and indeed the reliance on photo-responsive materials to carry out the operation ( Zhu et al, 2020 ; He et al, 2022b ), the photodynamic antibacterial method has drawn tremendous attention in microbiological applications ( Yang et al, 2018 ; Chauhan et al, 2019 ; Chen et al, 2019 ; Han et al, 2020 ; Zhao et al, 2022b ). Numerous cutting-edge substances, including nano-metal oxides ( Ning et al, 2017 ; Jin et al, 2019 ; He et al, 2022a ), two-dimensional (2D) materials ( Liu et al, 2016 ; Zhao et al, 2023 ), and other photosensitive substances ( Liu et al, 2019 ), can produce electron-hole pairs when exposed to certain wavelengths of light. The ejected electrons can then be captured by the oxygen in the environment to create reactive oxygen species (ROS), which can cause the death of pathogenic or diseased cells ( Chen et al, 2022a ; Zhou et al, 2022b ; Hu et al, 2023 ).…”

Pathogenic microbial infections have been threatening public health all over the world, which makes it highly desirable to develop an antibiotics-free material for bacterial infection. In this paper, molybdenum disulfide (MoS2) nanosheets loaded with silver nanoparticles (Ag NPs) were constructed to inactive bacteria rapidly and efficiently in a short period under a near infrared (NIR) laser (660 nm) in the presence of H2O2. The designed material presented favorable features of peroxidase-like ability and photodynamic property, which endowed it with fascinating antimicrobial capacity. Compared with free MoS2 nanosheets, the MoS2/Ag nanosheets (denoted as MoS2/Ag NSs) exhibited better antibacterial performance against Staphylococcus aureus by the generated reactive oxygen species (ROS) from both peroxidase-like catalysis and photodynamic, and the antibacterial efficiency of MoS2/Ag NSs could be further improved by increasing the amount of Ag. Results from cell culture tests proved that MoS2/Ag3 nanosheets had a negligible impact on cell growth. This work provided new insight into a promising method for eliminating bacteria without using antibiotics, and could serve as a candidate strategy for efficient disinfection to treat other bacterial infections.

“…Furthermore, the reversible metal–ligand bonding-ability of the Cp*M units also may enable to generate supramolecular structural transformations . Thus, various Cp*-based organometallic knots, , catenanes, Solomon links, Borromean rings, and ring-in-ring complexes were synthesized and their structural conversions were also studied. This advantage and results induced of Cp* groups offer great possibilities for the synthesis of more complex supramolecular complexes.…”

Self-Assembly and Photothermal Conversion of MetallaRussian Doll and Metalla[2]catenanes Induced via Multiple Stacking Interactions

A variety of organometallic supramolecular architectures have been constructed over the past decades and their properties were also explored via different strategies. However, the synthesis of metalla-Russian doll is still a fascinating challenge. Herein, a series of new coordination supramolecular complexes, including a metalla-Russian doll, metalla[2]catenanes, and metallarectangles, were synthesized by using meticulously selected Cp*Rh (Cp* = η5-C5Me5) building units (E1, E2, and E3) and three rigid anthracylpyridine ligands (L1, L2, and L3) via a self-assembly strategy. While the combination of the short ligand L1 and E1 or E2 generated two metallarectangles, the longer ligand L2 containing an alkynyl group resulted in two new [2]catenanes, most likely due to which the strong electron-donating effect of alkynyl groups causes self-accumulation. Interestingly, an unusual Russian doll assembly was obtained through the reaction of L3 and E3 based on sextuple π···π stacking interactions. Furthermore, the dynamic structural conversion between [2]catenanes and the corresponding metallarectangles could be observed through concentration-, solvent-, and guest-induced effects. The [2]catenane complexes 4b displayed efficient photothermal conversion efficiency in solution (20.2%), in comparison with other organometallic macrocycles. We believe that π···π stacking interactions generate active nonradiative pathways and promote radiative photodeactivation pathways. This study proves the versatility of half-sandwich building units, not only to build complicated supramolecular topologies but also in effective functional materials for various appealing applications.
