We report bromopyrogallol red (BPR) as an easily available dye for detection of copper and chloride with distinct visual color changes in DMSO/H(2)O (9:1 v/v). The chemosensor has a high chromogenic selectivity for Cu(2+) over other cations with detection limit of 0.07 μg mL(-1). The obtained complex of Cu(2+) with BPR displayed ability to detect Cl(-) up… CONTINUE READING
