Solvent-regulated fluorescence off–on signaling of Ni(ii) and Zn(ii) with the formation of two mononuclear complexes with an ATP detection ability by Zn(ii) assembly

Abstract

The current study shows that Schiff base HL, (Z)-2,4-dibromo-6-(((piperidin-2-ylmethyl)imino)methyl)phenol, can be used successfully as a selective chemosensor for Zn(II) and Ni(II) among several competing cations in purely aqueous and semi-aqueous...

Morphological adaptability through structural alterations in an AIE active novel chemosensor with Al(iii), Fe(iii), and gas phase/aqueous phase TNP recognition ability

“…‘S’ and ‘R’ in the subscript are the respective parameters for the studied sample and reference, respectively. 46…”

“…Scientists firmly believe that using organic chemosensors is the ideal approach for selective and easy detection of the said cations and explosives as it has several benefits, which include low cost, quick response times, minimal sample consumption, and accurate and selective detection. [17][18][19][20][21][22][23] In terms of detection, chemosensing has surpassed all the traditional detection approaches, including atomic absorption spectroscopy, inductively coupled plasma atomic emission spectrometry, chemiluminescence, voltammetry, and so forth, whose uses are restricted due to sophisticated instrumentation, high cost, and high sample and time consumption. 24,25 The quenching and the disappearance of emission intensity of fluorescent chemosensors in the solid or aggregated state is a major drawback.…”

Development of a novel AIE active piperazine appended chemosensor for solvent-regulated selective detection of IIB elements [Zn(ii), Cd(ii), Hg(ii)], Cl− and picric acid via varying emission colors to distinguish one another: environmental and biological applications

“…In diluted solutions, they quickly undergo CQN isomerization and are frequently non-fluorescent. 38,39 By restricting CQN isomerization via complexation with the analyte, the emissive property increases. Here, the non-radiative process could be stopped, resulting in the enhancement of fluorescence.…”

Polyurea-magnetic hierarchical porous composites for profiling of anionic metabolites

“…9 Current methods for anionic metabolites analysis mainly rely on uorescent sensors, chemosensors, and liquid chromatography tandem mass spectrometry (LC-MS/MS) with derivatization pretreatment. [10][11][12][13][14] Among them, LC-MS/MS analysis has attracted increasing attention for multidimensional qualitative and quantitative detection of anionic metabolites in complex samples and the discovery of biomarkers for the establishment of biomarkeromics, corresponding to specic diseases with high sensitivity and speci-city. Though the analysis efficiency and range of anionic metabolites has yet to be improved.…”
