Interestingly, sensor <b>L</b> 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 <b>L</b> 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.

Subsequently, solubility–temperature models including van’t Hoff equation, <i>λh</i> 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.

The maximum deviation observed in the density of the liquid solutions of methyl lactate with 1-heptanol was 0.28%, indicating the effectiveness of the CPA model in accurately modeling the density. Additionally, the researchers calculated the excess molar volumes and deviation in viscosity for the studied liquid mixtures. The analysis of these measurements revealed that the solutions of methyl lactate with 1-alkanols exhibited positive excess molar volumes across the entire concentration range. On the other hand, negative viscosity deviations were observed for the mentioned alkanols. These findings suggest that there are weak intermolecular associations within the liquid solutions, with weaker bond strength observed in higher alkanols.</p></div>","PeriodicalId":666,"journal":{"name":"Journal of Solution Chemistry","volume":"53 11","pages":"1462 - 1475"},"PeriodicalIF":1.4,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10953-024-01389-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141104357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
