A new benzothiazole-based fluorescent probe 2-(benzo[d]thiazol-2-yl)-4-(1,3- dithian-2-yl)phenol (BT) with two different reaction sites, a thioacetal group (site 1 for Hg ), and O and N atoms of the benzothiazole dye (site 2 for Cu ), was designed and synthesized. The probe BT showed ratiometric flu...
