“…[37] According to the FT-IR spectrum (Figure 2D), a strong peak appears between 1990 and 2140 cm −1 , which corresponds to the stretching vibration of N=C=S, and then the peak at 985 cm −1 corresponds to its bending vibration, further proving the existence of N=C=S in BFS. [32,38] The strong peaks located between 2860 and 3660 cm −1 and between 1580 and 1680 cm −1 correspond to the stretching and bending vibrations of O-H, respectively. [39,40] The UV-vis NIR absorption spectra of BFS are shown in Figure S4A, Supporting Information.…”

Infectious diseases caused by various bacteria pose a serious threat to human health, and the emergence of drug‐resistant bacteria has forced humans to develop new and effective antimicrobial agents and strategies. Herein, a metal–organic framework‐derived Bi2S3/FeS2 heterojunction (BFS) is synthesized, and the materials–microorganism interface is further constructed. Through interfacial electron transfer, electrons are transferred from the bacteria to the BFS surface, disrupting the balance of the bacterial electron transport chain and inhibiting the metabolic activity of the bacteria. Moreover, BFS has enzyme‐like (oxidase and peroxidase) properties and can produce a large amount of reactive oxygen species to kill additional bacteria. In vitro antibacterial results show that the antibacterial efficiency of BFS against both Staphylococcus aureus and Escherichia coli reaches more than 99.9% after 4 h of co‐culture under dark conditions. Meanwhile, in vivo experiments show that BFS can effectively kill bacteria and promote wound healing. This work shows that BFS could be a novel, effective nanomaterial for the treatment of bacterial infections by constructing the materials–microorganism interface.

“…So the coordination geometry around the Fe(III) ions can be described as slightly distorted square pyramidal geometry, τ = 0.018 (ideally τ = 0). [29,[40][41][42] There are no hydrogen bonds or significant intermolecular interactions in the crystal structure of [FeLCl]. Details of data collection and crystal structure determinations are given in Table 1.…”

The new symmetrical bisimine (ONNO donor, salen type) Ni(II), Zn(II), and Fe(III) complexes were synthesized in one step from metal ions and monoimine ligand (HL: 4-amino-3-{[(2-hydroxynaphthalen-1-yl)methylidene] amino}phenyl)(phenyl)methanone). The complexes were characterized by analytical, spectral, conductance, magnetic, and thermal data. According to these analysis results, while the bisimine ligand, spontaneously forming during complexation, is attached to the metal by two nitrogen atoms and two phenolic oxygen atoms (N 2 O 2 ) in all complexes, in the Fe(III) complex, the fifth coordination is completed by the chlorine molecule. A square pyramidal geometry for [FeLCl] and a square planar geometry for [NiL], [ZnL] were proposed. The three-dimensional structure of [FeLC1] was also evaluated by single-crystal Xray diffraction, and the square pyramidal structure was clearly revealed. The molar conductivity data of the complexes confirmed their nonelectrolytic nature. Poly(imine) (PL) was obtained by the oxidative polymerization reaction of HL, and some of its properties were investigated. The electrochemical properties of the ligand and the complexes were studied by means of cyclic voltammetry. Highest and lowest occupied molecular orbital (HOMO-LUMO) energy levels and electrochemical band gaps were calculated. The thermogravimetric analysis (TGA) and differential thermal analysis (DTA) of the synthesized compounds were carried out. TGA results showed that the thermal stability of the complexes is high. The solid-state electrical conductivities of the iodine doped states of the synthesized compounds were measured by the fourpoint probe technique. PL has approximately 35 times higher electrical conductivity than the HL and complexes. Fluorescence-sensor properties of HL were also investigated and predicted that HL could be a selective fluorescence probe for Pb 2+ .
