“…As one of the most sensitive probes, ethidium bromide binds to DNA by the intercalation mode 26. The intrinsic fluorescence intensity of DNA is very low and that of ethidium bromide in tris-HCl buffer is also not high because of solvent quenching, but the fluorescence intensity of ethidium bromide tends to increase when intercalatively bound to DNA due to its burial in the hydrophobic region of DNA. If the complex intercalates into DNA, it will lead to a decrease in the binding of ethidium bromide to DNA, hence quenching the fluorescence of the ethidium bromide-DNA mixture 27 . As shown in Fig.…”

The new ligand 2,2'-[2,3-naphthylenebis(oxy)]-bis(N,N-dibenzyl(acetamide) (L) and its Eu(III) and Tb(III) picrate complexes were synthesized. The complexes were characterized by elemental analysis, IR, TG-DSC and conductivity measurements. The luminescence properties of the two complexes were investigated. The result indicates that the triplet state energy level of the ligand matches better to the resonance level of Eu(III) than Tb(III) ion. Fluorescence intensity of the Eu(III) complex was reduced with the raising coordination ability of solvent. In addition, the DNA-binding properties of the two complexes have been investigated by electronic absorption, fluorescence and cyclic voltammetry. The results suggest that both complexes can bind to DNA via an intercalative binding mode and their binding affinity for DNA follows the order: Eu(III) complex > Tb(III) complex.
