Summary: Bacterial infections caused by biofilms are responsible for 80% of bacterial infections in humans. The use of self-assembled monolayers (SAMs) as a chemical strategy to combat biofilm formation shows promise due to their strong covalent bonds and versatile synthesis. This review focuses on the use of SAMs to inhibit biofilm formation and graft biocidal agents, with potential applications in indwelling medical devices. The challenges and future directions for this field are also discussed.

Summary: The study investigated the impact of surface-adsorbate interactions on the adsorption geometry of stilbene-NHCs monolayers and its influence on surface potential. It was found that stilbene-NHCs on Au film accumulated in a vertical orientation for high photoisomerization efficiency, while strong metal-adsorbate interactions on Pt film led to a flat-lying adsorption geometry that quenched the photo-induced response.

Summary: In this study, a carboxyl-modified 3-aminopropyltrimethoxysilane diffusion barrier was prepared using molecular self-assembly and graft modification technology. The barrier was coated with a copper film using RF magnetron sputtering. The results showed that carboxyl modification increased the thermal stability of the diffusion barrier, effectively inhibiting copper diffusion at high temperatures.

Summary: Novel uranium adsorbent AO-OB hierarchical self-assembled polyimide microspheres (AO-OBHSPIMs) were synthesized through molecule self-assembly and surface functionalization for the selective recovery of uranium from wastewater. AO-OBHSPIMs exhibited excellent selectivity to uranyl ions, good stability, recyclability, and high removal percentage in low-concentration solution and simulated uranium-containing wastewater. The adsorption mechanism of AO-OBHSPIMs was determined to mainly rely on electrostatic interactions and complexation in a spontaneous endothermic monolayer adsorption process. AO-OBHSPIMs showed promising application prospects in uranium-containing wastewater remediation.

Summary: Mixed self-assembled monolayers (SAMs) are commonly used as tunable substrates for biomedical and biosensing applications. This study investigates the impact of SAM structure and mixing ratio on the adsorption behavior of bovine serum albumin (BSA). The results show that the mixing ratio alone is a relatively good predictor of adsorption, regardless of the chain lengths of the thiols used in the mixture. There is no significant evidence that varying chain lengths of mixed SAMs have a large influence on nanoscopic adsorption behavior.

Summary: Eutectic Gallium-Indium (EGaIn) is a promising technique for fabricating self-assembled monolayers (SAMs)-based molecular devices, but previous measurements revealed abnormal signals, such as offset zero-bias current. A new automatic instrument platform was built to systematically study the electrical behavior of SAMs, showing that ambient water affects charge transport through molecular junctions and can cause offset of zero-bias current.

Summary: In this study, a series of carboxylic acid-functionalized porphyrin derivatives were designed and synthesized to improve the performance of perovskite solar cells (PSCs). The porphyrin derivatives not only reduced surface defects through the formation of self-assembled monolayers (SAMs), but also passivated the perovskite layer and facilitated hole transfer, leading to a highly efficient PSC with a solar efficiency of 23.19%. This work presents a novel molecular engineering strategy for functionalizing SAMs and provides valuable insights for future advancements in PSCs.

Summary: Tailored nano-spaces can control enantioselective adsorption and molecular motion through the spontaneous assembly of a dynamic system on Ag(111) using 2,6-bis(1H-pyrazol-1-yl)pyridine-4-carboxylic acid. The network cavity snugly hosts the chemically modified guest, bestows enantiomorphic adsorption, and allows selective rotational motions. Hydrogen bonding plays a crucial role in stabilizing the rotating guest and influencing the energy landscape formation.

Summary: By oxidative oligomerization of catecholic compounds, gelatin can be functionalized with caffeic acid (CA) oligomers to enhance its bioadhesive properties. Ex vivo adhesion tests on pig lungs showed a 33-fold improvement in adhesion strength compared to gelatin methacryloyl controls, with increased toughness and stretchability. Functionalization with CA oligomers also allows for rapid gel formation at room temperature, adjustable viscosity for injectability, and enhanced antioxidant effects.

Summary: Plasmonic gold nanoparticles have been increasingly used in solid-state systems for their applications in fabricating novel sensors, heterogeneous catalysts, metamaterials, and thermoplasmonic substrates. This review discusses a powerful synthetic methodology called bottom-up in situ substrate growth, which allows morphologically controlled nanostructures to be formed on supporting materials through wet-chemical synthesis. The review provides an overview of the properties of plasmonic nanostructures, recent advances in the understanding of in situ geometrical and spatial control, and the applications of plasmonic hybrid materials prepared by in situ growth. However, the mechanistic understanding of these methodologies remains incomplete and offers opportunities and challenges for future research.

Summary: Two new Schiff base mononuclear CuII and CoIII complexes were synthesized using monoethanolamine and o-vanillin as precursors. X-ray crystallography was used to study the structures of the complexes. Various experiments were conducted to analyze the binding of the complexes to DNA, and it was found that intercalation is the main mode of binding. The CuII complex showed better intercalation and induced double strand break in the presence of H2O2.

Summary: A new phase I" of ferrocene has been discovered, revealing the relationship between molecular conformation, intermolecular interactions, and electric permittivity. The conformational disorder of ferrocene molecules transforms into incommensurate modulation between 172.8 and 163.5 K. The structure of phase I" is described in the (3+2)-dimensional superspace, with modulation of molecular conformations, rotations and inclinations, Fe2+ cation displacements, and CH...π bonds in the crystal environment, leading to the bending distortion of FeCp2 and generation of molecular dipole moment waves.

Summary: A class of indenopyrroles was synthesized by the treatment of dihydroxy-2-methyl-4-oxoindeno[1,2-b]pyrroles with phosphorus oxychloride. The elimination of vicinal hydroxyl groups, formation of a p bond, and electrophilic chlorination produced fused aromatic pyrrole structures. Benzylic substitution of nucleophiles resulted in diverse 4-oxoindeno[1,2-b]pyrrole derivatives with yields of 58-93%. The reaction showed the highest yield when conducted in DMF. The structures of the products were confirmed using spectroscopic methods, elemental analysis, and X-ray crystallography.

Summary: This study presents a series of complexes with the cation [Ni(neoc)2(NO3)]+ and different counterions, including NO3-, TCNQ-, and (TCNQ-TCNQ)2-. By comparing the crystal structures of these complexes with analogous Mn, Fe, and Co compounds, a correlation between the coordination geometry of the nitrato ligand and the covalent radius of the central metal atom is revealed. The influence of different counterions on the crystal structure of the cation [Ni(neoc)2(NO3)]+ is also studied, showing that all complexes have supramolecular structures governed by hydrogen bonding systems, enhancing their stability.
