The synthesized fluorescent ligands 6 and 7 were characterized by H-1 NMR technique. The fluorescent study showed both water soluble ligands were Hg2+ selective and follow photo-induced electron transfer (PET) process. From the fluorimeter titration experiment detection limit was calculated as 1.14 x 10(-5) and 3.42 x 10(-5) for ligand 6 and 7, respectively. From the Benesi-Hildebrand plot binding constant values were evaluated as 666.7 and 733.3 M-1 for 6 and 7, respectively. The interactions between ligands 6 and 7 and Hg2+ were also demonstrated in living cells, SW-620, using Fluorescent Cell Imager. While ligands 6 and 7 alone show fluorescent properties, they loss their action with the presence of Hg2+ in SW-620 cells. (C) 2016 Elsevier B.V.
