Abstract:This novel oxime based fluorescent chemosensor (E)-2-(4'-(7,8,13,14-tetrahydrodibenzo[a,i]phenanthridin-5-yl)-[1,1'-biphenyl]-4-yl)ethen-1-ol (PBO) has been developed for the fluorimetric detection of hypochlorite ion (OCl−). On account of the optical behavior of the sensor PBO, distinctive...
“…Probe PDBT was used to detect CN − in Escherichia coli cells to test the bioimaging capabilities of the probe. 45 According to the bright eld diagram (Fig. 6a), it is clear that healthy cell morphology was seen in the experiment, showing that the probe was biocompatible and cytotoxicity-free.…”
(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.

“…The frontier molecular orbital (FMO) analysis of both chemosensors and the target analyte were optimised at the B3LYP/6-31G (d) level of theoretical analysis. 74 Fig. 5 depicts the HOMO–LUMO surfaces of the BIPP chemosensor.…”
“…Ratio-based fluorescent probes have become an increasingly popular research topic due to their ease of observation and low background interference caused by fluorescence changes. For example, Shirong Fang et al 39 and Saravanan Embanathan et al 40 synthesized HClO ratio probes with excellent properties. In this study, a novel ratio-based fluorescent probe (LW-1) was designed and synthesized for detecting hypochlorite using coumarin.…”
In this study, we designed and synthesized a novel ratiometric fluorescent probe, LW-1, using coumarin as a scaffold. LW-1 has the advantages of low detection limit, high sensitivity, good stability and low background interference.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
