Summary: In this study, a colorimetric fluorescent probe NI-CIN based on the intramolecular charge transfer mechanism was designed to specifically detect hydrazine. NI-CIN showed significant fluorescence enhancement and color change upon the addition of hydrazine, which could be observed by naked eye. Eco-friendly paper test strips were easily prepared using NI-CIN for real-time detection of hydrazine. NI-CIN also demonstrated potential applications in detecting hydrazine in water and soil samples, as well as bio-imaging in HepG-2 cells and zebrafish.

Summary: In order to address the issue of Cu2+ posing a threat to human health and the natural environment due to its widespread use in various industries, researchers have developed a chitosan-based fluorescent probe CTS-NA-HY for the detection and adsorption of Cu2+. CTS-NA-HY showed a specific turn off fluorescence response to Cu2+ and changed color from bright yellow to colorless. It demonstrated good selectivity and anti-interference, a low detection limit (29 nM), and a wide pH range (4-9) for Cu2+. Furthermore, the probe was capable of determining Cu2+ in environmental water and soil samples.

Summary: Based on the N-redox mechanism, a turn-on near-infrared fluorescence probe (SWJT-15) with cyano isophorone as the skeleton was synthesized for the detection of ferrous ions (Fe2+). The probe showed a lower detection limit (83 nM) and fast response (200 s) to Fe2+ ions. It demonstrated unique selectivity and good anti-interference performance against Fe2+ ions compared to other metal ions. Moreover, the probe was successfully applied for imaging Fe2+ ions in HeLa cells.

Summary: In this paper, a new rhodamine derivate was synthesized and used as a phosgene probe with highly rapid, special and sensitive response towards phosgene. A fluorescent detection pen with gas-liquid reaction model was proposed for the first time to achieve in situ visualization of phosgene. The detection film could be formed in situ by simply writing on desired surface and respond toward phosgene gas within 30 s with an ultra-low detection limit (2 ppm) with the naked eye. Such a fluorescence pen detection mode provided an excellent platform for real-time detection of phosgene and other gas analytes.

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.
