Aniline trimer based chemical sensor for dual responsive detection of hazardous CN¯ ions and pH changes

Stimuli-directed selective detection of Cu2+ and Cr2O72− ions using a pH-responsive chitosan-poly(aminoamide) fluorescent microgel in aqueous media

“…8–11 Without the help of highly expensive instruments like atomic absorption spectroscopy (AAS), and inductively coupled plasma-mass spectrometry (ICP-MS), the fluorescence-sensor based metal ion detection technique is a straightforward and low-cost process and therefore, the development of such sensors has attracted much attention. 12,13 In this context, several advanced functional materials such as carbon dots, 14,15 quantum dots, 16,17 metal ion based fluorophores, 18–20 polymers, 21–25 small molecular organic probes, 26–28 micelles 29 and microgels 30,31 are reported. In most of the cases, such fluorophores can selectively detect a single ion.…”

A One‐Pot Synthesized Chemodosimetric Chemosensor for Highly Sensitive Cyanide Ion Detection in Aqueous Media and from Tobacco Smoke

“…[7,8] Multiple dedicative attempts in the past were undertaken to detect the cyanide ion in the commercial samples by synthesizing different chemo sensors through colorimetric and fluorimetric detection technique. [9][10][11] However, a synthetic procedure is not commercially viable and tedious process have a serious drawback. [12][13][14] Especially the synthesised probe PYRÀ TZ shows a turn-on fluorescence response upon addition of cyanide ion, which further strengthen the evaluation of trace amount of cyanide in the sample.…”

Schiff base derived from salicylaldehyde‐based azo dye as chromogenic anionic sensor and specific turn‐on emission sensor for cyanide ion

“…Anion sensing and detection have been a progressing arena in the field of host‐guest interaction studies in the last two decades . This approach has overwhelming applications in the medical, biological, environmental, and industrial areas.…”
