Abstract
Abstract 1,4-Bis[2-aminoethylamino]anthracene-9,10-diones selectively bind with Cu 2+ to form complexes with unusual selectivity under basic conditions. The deprotonation of the aryl amine NH in the case of these chemosensors causes a bathochromic shift in the absorption band from 585 nm and 635 nm to 725 nm and enables ratiometric estimation of Cu 2+ between pH 8 and 12.
