A phenanthridine-based probe for selective detection of hypochlorite ions

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...

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

“…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.…”

Zinc ion detection using a benzothiazole-based highly selective fluorescence “turn-on” chemosensor and its real-time application

“…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.…”

Development of a novel hypochlorite ratio probe based on coumarin and its application in living cells

“…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.…”
