Summary: In this study, fluorogenic coumarin-based probes were synthesized by condensation reaction of 4-hydroxy coumarin with malondialdehyde bis(diethyl acetal)/triethyl orthoformate. The absorption and fluorescence emission properties of probes 2b and 3 in different solvents were investigated, showing significant solvatochromic effect. Chemosensors 2b and 3 exhibited selectivity towards various cations and anions, with compound 3 showing distinct selectivity towards Sn2+ via chelation enhanced quenching mechanism. The fluorescence signal of compound 3 was quenched in the concentration range of 6.6-120 μM, with a detection limit of 3.89 μM. The non-toxicity and successful application of compound 3 in cellular imaging were demonstrated. The probe not only responded to tin ions through fluorescence quenching, but also showed colorimetric signal change, which could be observed in ambient conditions and inside living cells.

Summary: Deep eutectic solvents (DESs), also known as low transition temperature mixtures (LTTMs), have emerged as sustainable and cheap alternatives to conventional organic solvents in organic synthesis. DESs possess exceptional characteristics such as easy preparation, water compatibility, non-flammability, non-toxicity, biocompatibility, and biodegradability, making them versatile and cost-effective green solvents. Choline chloride-based DESs have been extensively utilized as harmless solvents and catalysts in the synthesis of various heterocyclic compounds, showing excellent yields, shorter reaction times, and a simple workup procedure.

Summary: In this study, a self-limiting method using agarose gel was proposed to prepare bimetallic (iron and cobalt) nitrogen-doped carbon composites (FeCo-NC) as efficient electrocatalysts. The optimized FeCo-NC catalyst exhibited a small potential difference between the oxygen reduction reaction (ORR) half-wave potential and the oxygen evolution reaction (OER) potential, and demonstrated excellent performance in Zn-air batteries. This research provides an effective means of designing electrocatalysts and energy conversion systems.
