array of fluorogenic probes is able to discriminate between nerve agents, sarin, soman, tabun, VX and their mimics, in water or organic solvent, by qualitative fluorescence patterns and quantitative multivariate analysis, thus making the system suitable for the in-the-field detection of traces of chemical warfare agents as well as to differentiate between the real nerve agents and other related compounds
A quinoline-indene derivative is described as a new highly selective and sensitive chromogenic and turn-on fluorogenic probe for the naked-eye detection of copper(II) cation in water−acetonitrile 1:1 mixture.
