Moisture or trace water detection at a very low level in organic solvents and other chemical reagents has great significance in the chemical and industrial process. At present, reports on chemical sensors for moisture are still in the early development phase and need continuous improvements. Recently, several approaches have been proposed for the easier detection of water content in the organic solvents. In this review article, we have summarized recent reports on chemical sensors used to detect water in organic solvents. The discussion is focused on optical methods, including fluorescent and colorimetric probes exploring solvatochromism, displacement of ligand or metal and water-induced protonation. Besides, water detection in organic solvents by NMR spectroscopy is also discussed. Probe structure, sensitivity with organic solvents, spectroscopy detection limits, and possible application in various other research areas, including ink-less writing, sweat pore mapping, food products and engineering materials are described in detail.

“…1d). The uorescence quantum yield (F ¼ 0.93) of Probe 1 solution without HOCl was calculated with 9,10-diphenylanthracene (F F ¼ 0.95 in ethanol) 42 as the reference uorescence standard substance. This can be attributed to the strong electrondonating ability of S atoms in methyl sulde, which is transferred to the naphthalene imide through ICT process, thus making the uorescence quantum yield of Probe 1 extremely high.…”
