Active Bromoaniline-Aldehyde Conjugate Systems and Their Complexes as Versatile Sensors of Multiple Cations with Logic Formulation and Efficient DNA/HSA-Binding Efficacy: Combined Experimental and Theoretical Approach.

ABSTRACT: Two fluorescence active bromoaniline-based Schiff base chemosensors, namely, (E)-4-bromo-2-(((4-bromophenyl)imino)methyl)phenol (HL₁ ) and (E)-2-(((4-bromophenyl)imino)methyl)phenol (HL₂ ), have been employed for the selective and notable detection of Cu²⁺ and Zn²⁺ ions, respectively, with the simultaneous formation of two new metal complexes [Cu(L₁)₂] (1) and [Zn(L₂)₂] (2). X-ray single crystal analyses indicate that complexes 1 and 2 are tetra-coordinated systems with substantial CH...π/π...π stacking interactions in the solid-state crystal structures. These two complexes are exploited for the next step detection of Al³⁺ and Hg^2+<
