This microextraction method uses a unique task-specific ionic liquid (IL) as the specific complexing agent and/or extracting phase. A pyrrolidinium-based IL modified with (E)-5-(bromomethyl)-2-(pyridin-2-yldiazenyl) phenol as a task-specific IL (E)-1-(3-hydroxy-4-(pyridin-2-yldiazenyl) benzyl)-1-methylpyrrolidinium bromide (TSIL/Br) was successfully synthesized and characterized by 1HNMR and FTIR analyses. TSIL/Br chelated with U(VI) ions in the aqueous phase to form a hydrophilic [U(VI)-TSIL/Br2] complex with high efficiency. It was then converted to a hydrophobic [U(VI)-TSIL/(NTf2)2] complex through a counter-ion agent, such as bis(trifluoromethanesulfonyl)imide ((text{NTF}_2^-)) for separation from the aqueous solution phase. This process eliminates the need for a separate complexing agent, because TSIL/Br acts simultaneously as both a complexing agent and an extracting solvent. In brief, the conditions of the microextraction process must be optimized for the analysis of real water samples.

In this paper, a dual-response sensor for pH detection, [1,2']biindenylidene-3,1',3'-trione L, was synthesized from substrate indane-1,3-dione, and its structure was confirmed by 1H NMR, 13C NMR, ESI–MS and single crystals. Interestingly, sensor L exhibits solvatochromic properties and visualized color changes at different poplar solutions, and it can show significant changes in fluorescence intensity, UV–Vis absorbance and color at moderate acidic (pH = 3.52–5.03) and strong basic conditions (pH = 13.09–13.27) based on intramolecular proton transfer (IPT) mechanism. These results indicate that L can act as a double functional probe for the analysis and visual detection of pH change under moderate acidic and strong basic conditions in a quite narrow pH range. In addition, L can also selectively identify solvent CH2Cl2 by inducing larger blue-shift in wavelength and increase in fluorescence intensity, which means that it may be used as an indicator for monitoring trace amount of CH2Cl2. The potent applicantions for sensor L were also investigated and that it could conveniently be made into a series of strips for pH detection was indicated.</div>","PeriodicalId":666,"journal":{"name":"Journal of Solution Chemistry","volume":"53 11","pages":"1476 - 1491"},"PeriodicalIF":1.4,"publicationDate":"2024-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141375621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the selected binary solvents, the solubility of SDP increased with the rise in temperature and initial methanol composition of binary solvents, and the general order of solubility of SDP under the same conditions was: (methanol + ethanol) > (methanol + n-propanol) > (methanol + i-propanol). Subsequently, solubility–temperature models including van’t Hoff equation, λh equation, Yaws equation, and Apelblat equation; solubility–solvent composition models including general single model; solubility–temperature and solvent composition models including NRTL equation and modified Jouyban–Acree model were used to correlate the solubility data. Regarding the application of the NRTL equation in binary solvent systems, the influence of solvent composition on model parameters was first taken into account by introducing a solvent composition correction factor, thereby exhibiting an enhancement in fitting accuracy. To gain deeper insights into the dissolving behavior of SDP, molecular electrostatic potential surface, Hirshfeld surface analysis and the KAT-LSER model were applied to analyze the molecular interactions between SDP molecules and the solvent effects. Meanwhile, entire solubility data in three binary solvent systems at 298.15 K were associated as a function of solvent properties on the basis of KAT-LSER model.
