Summary: Natural capsaicin and its derivatives can impede marine organisms and achieve antifouling effects without killing marine fouling organisms. Certain derivatives were found to have good antibacterial and algal inhibitory properties. When added to marine antifouling coatings, these compounds demonstrated a good antifouling effect, providing a feasible direction for the development of environmentally friendly antifouling coatings.

Summary: Water pollution with toxic heavy metals or antibiotics poses a significant safety risk to human survival and health. Luminescent metal-organic frameworks (LMOFs) have been developed as efficient sensors for detecting these contaminants. A new 2D Cd-LMOF LCU-125 has been fabricated with rich amide active functional sites, serving as a multi-responsive luminescent sensor. LCU-125 can selectively and sensitively detect Fe3+, Cr2O72-, and OTC through a quenching effect in both water and HEPES biological buffer solution, with low detection limits for these substances.

Summary: Novel stationary phase Sil-Ala-C18, derived from beta-alanine with embedded urea and amide groups, has been prepared and evaluated for its chromatographic performance. The new phase demonstrated excellent separation capabilities for nonpolar shape-constrained isomers, polar and basic compounds in reversed-phase liquid chromatography (RPLC), and highly polar compounds in hydrophilic interaction liquid chromatography (HILIC) compared to commercial reference columns. Additionally, it successfully separated the challenging beta- and gamma-isomers of tocopherol and was applied to the separation of tocopherol isomers and capsaicinoids in real chili pepper samples in RPLC, as well as ascorbic acid (vitamin C) in HILIC.

Summary: Research on small molecules-based optoelectronic devices has shown that improving device performance can be achieved by increasing the conjugation length in organic semiconductors, extending molecular ordering and intermolecular interactions through hydrogen bonding. However, solubility remains a challenge for the application of these materials, and cleavable protecting groups are used to address this issue.

Summary: The design and development of materials with a selective adsorption capacity for Pb(II) is crucial for environmental governance and ecological safety. In this study, a novel 3D metal-organic framework (Cd-MOF) was constructed using a multiple pyrazole heterocycles tetraphenylethylene-based ligand (H4L4) and CdSO4, which exhibited excellent stability and a high adsorption capacity for Pb(II). The Cd-MOF showed a maximum adsorption value of 845.55 mg/g, higher than most other MOFs or MOFs modified materials. It also demonstrated remarkable recyclability due to its unique adsorption mechanism. Thermodynamic studies revealed that the adsorption of Pb(II) by Cd-MOF is a spontaneous endothermic process. These features make Cd-MOF a potential material for industrial capture and recovery of Pb(II) from water.

Summary: The high-barrier polyimide (NAPPI) with naphthalene ring and amide group exhibits superior barrier properties, mechanical properties, and thermal stability. Experimental and simulation studies confirm that the small interplanar spacing and high chain regularity of NAPPI play a key role in its barrier properties, while the strong chain rigidity and interchain cohesion due to the presence of the rigid naphthalene ring and hydrogen bond interactions formed by amide groups result in compact chain packing and smaller free volume, reducing the solubility and diffusibility of small molecules in the matrix.

Summary: Polymeric materials are considered a promising option for solid-state lithium batteries due to their superior energy and power densities, long cycle lives, and high safety. This study focused on the impact of the side-chain structure on intermolecular interactions within the polymer, aiming to enhance the ionic conductivity of polymer electrolytes. Through spectro(electro)chemical analysis, it was found that the cyanoethoxy side-chain effectively improved Li+ conduction by breaking hydrogen bond network and dipole interactions.

Summary: In this study, crosslinked polycarboxylate superplasticizers were synthesized using different crosslinking agents, and their performance was characterized. It was found that superplasticizers containing ester groups exhibited better dispersibility, fluidity retention, and adsorption capacity than those containing amide groups. Additionally, the ester-based superplasticizers promoted cement hydration to a greater degree than their amide-based counterparts.

Summary: Two new isostructural 3D lanthanide metal-organic frameworks (Ln-MOFs), [Ln(2)(L)(3)(H2O)(2)]center dot 2H(2)O center dot 2DMF (1-Ln, Ln = Eu3+ and Tb3+, H2L = 5-triazole isophthalic acid) were successfully synthesized via solvothermal reaction, with uncoordinated triazole groups decorating the channels. Luminescence studies reveal that 1-Eu and 1-Tb as fluorescent probes exhibit high sensitivities and excellent selectivities towards nitroaromatics (NACs) and Fe3+ in DMF system by luminescence quenching process. The quenching mechanisms were investigated through PXRD, DFT theory calculation, XPS, UV-vis and discussed in details.

The structure of compound 3 was found to involve a CO2 insertion between positions 3 and 4 of compound 2a. The selectivity and kinetic behavior of compound 3 and another compound (5) were also reported.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
