Novel N,N′‐Diacylhydrazine‐Based Colorimetric Receptors for Selective Sensing of Fluoride and Acetate Anions

Bioinspired aerogels: ingenious structure, remarkable performance, and versatile applications

“…The development of nuclear energy has effectively alleviated the global energy crisis over the past few decades, resulting in vast uranium consumption and the accumulation of uranium waste. 143 The increasing demand for uranium and the potential threat to public health from uranium contamination emphasize the need for sustainable uranium extraction technologies. 144 Taking inspiration from water vapor transpiration and the porous structure of hydrilla, Li et al designed and synthesized green tea waste/graphene aerogels (GDTs) with a hierarchical structure and photothermal conversion properties for uranium capture (Fig.…”

Optical detection of sodium salts of fluoride, acetate and phosphate by a diacylhydrazine ligand by the formation of a colour alkali metal complex

“…L was synthesized by a modified literature procedure (scheme 1). 7 To a solution of hydrazine hydrate (0.4 ml) in dry THF was added triethylamine (3.2 ml) in ice cold condition and the solution stirred for 15 min. To the stirred solution 4-nitrobenzoyl chloride (3 g) in dry THF was added, a yellow precipitate appeared after sometime and the solution was stirred overnight and finally refluxed for 3 h. The whole solution was then evaporated in vacuo and thoroughly washed with H 2 O to remove triethylammonium chloride and excess acid…”

Molecular Details of Acetate Binding to a New Diamine Receptor by NMR and FT-IR Analyses

“…Several spectroscopic methods and techniques are popular to investigate the receptor/ion interactions including UV–visible spectral changes, , colorimetric − change, and fluorescence change . Many examples of both colorimetric and fluorescent chemosensors , for acetate anion are reported.…”
