Novel Chemosensor for the Visual Detection of Copper(II) in Aqueous Solution at the ppm Level

A new water-soluble, multisite-coordinating ligand LH7 was prepared by the condensation of tris(hydroxymethyl)aminomethane with 2,6-diformyl-p-cresol. LH7 is a selective chemosensor for Cu2+, under physiological conditions, with visual detection limits of 20 ppm (ambient light conditions) and 4 ppm...

Description
Summary:A new water-soluble, multisite-coordinating ligand LH7 was prepared by the condensation of tris(hydroxymethyl)aminomethane with 2,6-diformyl-p-cresol. LH7 is a selective chemosensor for Cu2+, under physiological conditions, with visual detection limits of 20 ppm (ambient light conditions) and 4 ppm (UV light conditions). LH7 can also be used in biological cell lines for the detection of Cu2+.
