Liquid metal-embedded magnetic hydrogel beads as novel adsorbents for malachite green removal.

Malachite green (MG) is widely used in aquaculture as a parasiticide. It has generated much concern due to its carcinogenesis, mutagenesis, chromosomal fractures, teratogenicity, and respiratory toxicity. Effective methods for removing MG from water or other media are highly needed.

Hierarchical assembly of Ag nanowheel ranging from building blocks to diverse superstructure regulation.

Achieving precise and controllable hierarchical self-assembly of functional nanoclusters within crystal lattices to create distinct architectures is of immense significance, yet it creates considerable challenges. Here we successfully synthesized a silver nanowheel Ag, along with its optically pure enantiomers S-/R-Ag Each species possesses an internal nanospace and exhibits host-guest interactions. These structures are constructed from primary building blocks (Ag).

Construction of novel Ag(0)-containing silver nanoclusters by regulating auxiliary phosphine ligands.

Controlled synthesis of metal clusters through minor changes in surface ligands holds significant interest because the corresponding entities serve as ideal models for investigating the ligand environment's stereochemical and electronic contributions that impact the corresponding structures and properties of metal clusters. In this work, we obtained two Ag(0)-containing nanoclusters (Ag17 and Ag32) with near-infrared emissions by regulating phosphine auxiliary ligands. Ag17 and Ag32 bear similar shells wherein Ag17 features a trigonal bipyramid Ag kernel while Ag32 has a bi-icosahedral interpenetrating an Ag kernel.

Highly Efficient Circularly Polarized Luminescence from Chiral Au Clusters Stabilized by Enantiopure Monodentate NHC Ligands.

Chiral Au nanoclusters have promising application prospects in chiral sensing, asymmetric catalysis, and chiroptics. However, enantiopure superatomic homogold clusters with crystallographic structures emitting bright circularly polarized luminescence (CPL) remain challenging. In this study, we designed chiral N-heterocyclic carbenes (NHCs), and for the first time enantioselectively synthesized a pair of monovalent cationic superatomic Au clusters.
