Summary: Designing fluorescent sensors for selective detection of CN- in aqueous and even solid states is a challenge due to the aggregation-caused quenching (ACQ) effect. The novel fluorescent probe C-1 reported in this paper exhibited orange-red fluorescence with emission peak centered at 597nm in aqueous solution and solid state, making it a selective CN-sensor with sensitivity and detection limit of 5.97 x 10(-4) M-1 and 1.2 mu M respectively. The interactions between C-1 and CN- were confirmed by UV-visible and fluorescent measurements, and the H-1 NMR titration method demonstrated the detection mechanism.

Summary: Cysteine plays an important role in the human body, and abnormal concentration can lead to various diseases. Detecting cysteine in vivo with high selectivity and sensitivity is therefore significant. In this study, a small organic fluorescent probe ZHJ-X was designed and synthesized based on cyanobiphenyl, which specifically recognized cysteine. The probe ZHJ-X demonstrated specific selectivity, high sensitivity, short response time, good anti-interference ability, and a low detection limit of 3.8 x 10-6 M. It was successfully applied for visualizing cysteine in living cells and holds potential for cell imaging and detection.

Summary: This paper presents a method for developing a fluorescent chemosensor for Fe3+ ions using hydrophilic carbon dots, synthesized from Oxalis corniculata through a simple, cost-effective, and environmentally friendly hydrothermal synthesis process. The resulting O-CDs exhibit good physical and chemical properties, high quantum yield, and stable fluorescence, making them suitable for sensitive and selective detection of Fe3+ ions in aqueous solutions. This nanosensor shows promise for biomedical applications due to its high biocompatibility and cellular imaging capabilities.

Summary: Graphdiyne-based copper oxide quantum dots were used as cathodic electrodes and water as the hydrogen source to achieve the electrocatalytic hydrogenation of purely aliphatic and functionalized olefins in aqueous solution at high current density under ambient temperature and pressure, showing high activity and selectivity. The incomplete charge transfer between graphdiyne and copper atoms due to the chemical and electronic structure of graphdiyne optimized the adsorption/desorption of reaction intermediates, resulting in high selectivity and activity for hydrogenation reactions.

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.
