Determination of Water Content in Organic Solvents by Naphthalimide Derivative Fluorescent Probe

Improving Fluorometric Determination of Water Content in Aprotic Solvents

“…The high sensitivity offered by the system based on application of 4-MU (Kłucińska et al 2015) was extended for higher contents of water in the samples, i.e., for the range inaccessible for the system using only one dye. It should be stressed that linear response range and detection limit were well comparable to the literature reports using other fluorimetric approaches for determination of water in organic solvents, e.g., in dioxane where linear response of the probe covered the water content to 4.00% V/V (DL (%) = 0.019) (Niu et al 2010) or with the use of fluorescent nanospheres (Gao et al 2009 intensity on water contents in ethanol was observed in the range from 0.05 to 6.0% V/V).…”

“…Different dyes have been proposed/tested in this respect, most of them were tailor made (synthesized) for water determination purpose, and in most cases, the increase of water contents in the sample was accompanied with Electronic supplementary material The online version of this article (doi:10.1007/s12161-017-1019-7) contains supplementary material, which is available to authorized users. decrease (quenching) of emission signal (e.g., Yunxiang and Xin 1984;Gao et al 2009;Niu et al 2010), which is clearly unfavorable for practical purposes.…”

7-Dialkylaminocoumarin Oximates: Small Molecule Fluorescent “Turn-On” Chemosensors for Low-Level Water Content in Aprotic Organic Solvents

“…A qualitative and quantitative detection of low-level water present as an impurity in organic solvents has great significance in several fields of chemistry and industry processes (pharmaceutical manufacturing, food processing, production of anhydrous solvents and chemical reagents, petroleum fuel industry, paper production and biomedical or environmental monitoring) [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ]. Many analytical approaches and techniques have been established for the determination of water in a wide variety of organic solvents, such as Karl Fischer titration and gas chromatography methods on the laboratory scale, and electrochemical/electrophysical methods particularly for large-scale industry processes.…”

“…However, electrical sensors suffer often from the lack of insufficient portability/precision and exhibit undesirable sensitivity to electromagnetic interference [ 4 ]. Laboratory methods have the disadvantage of requiring time-consuming sample preparation, inability of real-time monitoring of the water content, a need for skilled personnel and special equipment and interference from other co-existing species [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ]. Moreover, the Karl–Fisher titration is less sensitive in aprotic and non-alcoholic solvents [ 19 ].…”

Fluoranthene dyes for the detection of water content in methanol

“…Numerous probes have been designed based on a variety of dyes and fluorophores. In fact, fluorescent sensors for the sensitive sensing of the water content in organic solvents have been successfully designed using various fluorophores of 1,8-naphthalimide, 13–15 flavone derivatives, 16 8-hydroxyquinolines, 17 2,3-biphenyl quinoxaline 6-amine, 18 thioxanthone fluorophores, 19,20 poly( m -aminobenzoic acid) 11,21 and acridine orange-based optical fiber. 22–24 However, comparatively very little attention has been devoted to the interesting photophysical and optical properties of highly fluorescent organic dyes, fluoranthene derivatives.…”
