Synthesis, Crystal Structure, and DNA-Binding Studies of a Nickel(II) Complex with the Bis(2-benzimidazolymethyl)amine Ligand

Figure 3

Emission spectra of EB bound to DNA in the presence of the complex. [Complex] = 3×10⁻³ M; 𝜆_ex = 520 nm. The arrow shows the intensity changes upon increasing concentrations of the complex. Fluorescence quenching curves of EB bound to CT-DNA by the Ni(II) complex. (Plots of 𝐼₀/𝐼 versus [Complex]/DNA.).
