Advancement in fluorescent chemosensor for discriminative and precise detection of picric acid (PA) aqueous medium is highly desirable owing to its alarming impact on the natural environment via soil groundwater pollution. To this end, we have successfully fabricated a quinoxaline-based receptor (Probe 1) detect PA 100% medium. Probe 1 self-assembled form leaf-like structures pure water as micr...

Chemical sensors based on fluorescent quantum dots have attracted intense interest because of their excellent optical and electronic properties compared to the routinely employed organic dyes. This study reports a CdSe QD-polymer-based luminescent chemosensor, which is an array containing either green-emitting or red-emitting QDs embedded in polycaprolactone as polymer host matrix. We evaluate ...

A graphene oxide-terpyridine conjugate (GOTC) based colorimetric and fluorescent nano-chemosensor was synthesized. It showed high selectivity and sensitivity for Fe2+ and Fe3+ ions in neutral aqueous solution over other metal ions such as Li+, Na+, Ba2+, Ca2+, Al3+, Cd2+, Co2+, Cu2+, Hg2+, Mn...

Rhodamine B thiolactone is developed as a simple chemosensor towards Hg(2+) in neutral aqueous solution with high selectivity.
