Facile detection of organophosphorus nerve agent mimic (DCP) through a new quinoline-based ratiometric switch

Autor: Krishnendu Aich, Saswati Gharami, Lakshman Patra, Tapan Kumar Mondal, Sangita Das

Publikováno v: New Journal of Chemistry. 43:8627-8633

In this paper, a quinoline-based (BIMQ) probe was developed, and it displayed ratiometric detection of organophosphorus (OP) chemical vapor threat DCP. Upon addition of the nerve agent mimic diethyl chlorophosphate (DCP), a fluoroscence color change

Simple fabrication of a carbaldehyde based fluorescent 'turn-on' probe for the selective and sole detection of Pd2+: application as test strips

Autor: Saswati Gharami, Tapan Kumar Mondal, Krishnendu Aich, Chandan Kumar Manna, Lakshman Patra

Publikováno v: New Journal of Chemistry. 43:16915-16920

A new fluorescent “turn-on” probe (DHMC) has been designed and synthesized to selectively detect Pd2+ among other cations at physiological pH. Upon incremental addition of Pd2+ into the probe solution, a “turn-on” emission enhancement was not
