A New Reversible Colorimetric Chemosensor Based on Julolidine Moiety for Detecting F−

Autor: Boeon Suh, Cheal Kim, Dongkyun Gil

Publikováno v: Journal of Fluorescence. 31:1675-1682

We synthesized an original reversible colorimetric chemosensor PDJ ((E)-9-((2-(6-chloropyridazin-3-yl)hydrazono)methyl)-2,3,6,7-tetrahydro-1H,5H-pyrido[3,2,1-ij]quinolin-8-ol) for the detection of F−. PDJ displayed a selective colorimetric detectio

Colorimetric detection of Cu2+ using of a mixture of ponceau 6R and a cationic polyelectrolyte in aqueous solution

Autor: Shunichi Aikawa, Yasumasa Fukushima

Publikováno v: Journal of Inclusion Phenomena and Macrocyclic Chemistry. 100:143-148

A colorimetric chemosensor is reported for Cu2+ by a simple mixture of two commercially available reagents, ponceau 6R (P6R) and poly(diallyldimethylammonium chloride) (PDADMAC) in an aqueous solution. P6R interacted electrostatically with PDADMAC to
