Benzothiazole appended 2,2′-(1,4-phenylene)diacetonitrile for the colorimetric and fluorescence detection of cyanide ions

Abstract

(2Z,2′Z)-2,2′-(1,4-Phenylene)bis(3-(3-(benzo[d]thiazol-2-yl)-4-hydroxyphenyl)acrylonitrile) (PDBT) has been synthesized and investigated as a novel PDBT, capable of showing high selectivity and sensitivity towards CN− over a wide range of other interfering anions.

D–π–A–π–D-Configured Imidazole-Tethered Benzothiadiazole-Based Sensor for the Ratiometric Discrimination of Picric Acid: Applications in Latent Fingerprint Imaging

“…As shown in Figure S9, free sensor BIPT experienced a trivial influence on fluorescence intensity with stable irradiation coupled with the excitation wavelength. After adding PA, the fluorescence intensity escalated and attained a plateau after 5 s. 54 This finding demonstrates that BIPT can effectively detect PA with good stability.…”

Naphthyl-azine – aggregation induced emission, reversible acidochromism, cyanide sensing and its application in intracellular imaging

“…S16(a) and (b), ESI †). 70 1 H NMR titration of H 2 L with CN À 1 H NMR titration of the probe with CN À in DMSO-d 6 explains the interaction of the probe in the presence of varying concentration of CN À . On addition of 1 equivalent of CN À , the intensity of the phenolic protons (OH (1,10)) at 12.72 (naphthyl-OH) and 12.26 ppm (dimethoxyphenyl-OH) diminishes, and it completely vanishes upon addition of 2 equivalents of CN À (Fig.…”
