چکیده

Sugar-aza-crown ether-based cavitand 1 can act as a selective turn-on fluorescence sensor for hydrogen sulfate ion in methanol among a series of tested anions. Spectroscopic studies, particularly NMR spectroscopy, revealed that the C-H hydrogen bonding between 1,2,3-triazole ring of cavitand 1 and hydrogen sulfate ion is crucial for the high selectivity of the receptor for hydrogen sulfate.

A Dual colorimetric and Fluorometric Anion Sensor Based on Polymerizable 1, 8-Naphthalimide Dye

A new polymerizable fluorescent sensor based on the photoinduced electron transfer PET for the selective determination of fluoride ions in DMF solutions has been synthesized. The sensing system was prepared by incorporating 4-Amino-1,8-naphthalimide derivatives containing thiourea side chain at the amino moiety AFTN as a neutral F- selective flourophore and was characterized by use of the DSC, ...

Squaramide-based tripodal ionophores for potentiometric sulfate-selective sensors with high selectivity.

A class of squaramide-based tripodal molecules was employed as new ionophores for highly sensitive and selective sulfate-selective sensors. Compared with the reported tripodal ionophore with urea, squaramide groups as superior hydrogen bonding donor were introduced into the tripodal structure to obtain new ionophores leading to better electrode performance. Three derivatives with unsubstituted ...

A New Colorimetric Azo-azomethine Probe for Fluoride Ion Detection Based on the Proton Transfer Signaling Mode: Real-life Applications

Four novel receptors were designed and synthesized for colorimetric detection of F− ions. The introduction of four electron withdrawing groups into the backbone of the receptors makes the two phenolic groups efficient hydrogen bonding sites. The binding properties of receptors with anions were examined for the first time by UV–Vis, 1H NMR and fluorescence spectroscopies. The addition of F− resu...

Studies on quenching of fluorescence of reagents in aqueous solution leading to an optical chloride-ion sensor

The sensitivity of quinolineand acridine-type indicators towards the detection of low levels of chloride ions in aqueous and amine-doped media, by fluorescence quenching, is reported in this paper. Solution studies are based on the fluorescence of quinine sulphate, acridine and 3(6-methoxyquinolino) propanesulphonate (SPQ) and the fluorescence response of these indicators has been examined at d...

Fluorescence ratiometric sensor for trace vapor detection of hydrogen peroxide.

Trace vapor detection of hydrogen peroxide (H2O2) represents a practical approach to nondestructive detection of peroxide-based explosives, including liquid mixtures of H2O2 and fuels and energetic peroxide derivatives, such as triacetone triperoxide (TATP), diacetone diperoxide (DADP), and hexamethylene triperoxide diamine (HMTD). Development of a simple chemical sensor system that responds to...
