Nickel(II) Complexes Derived from Schiff Base Ligands Designed as Electrode Materials in Asymmetric Supercapacitor Coin Cells for Enhanced Energy Storage Performance.

ABSTRACT: In this study, three nickel(II)-based Schiff base complexes, derived from the condensation of 2-hydroxybenzaldehyde with 2-bromo-4-chloroaniline (C1), 2-bromo-4-methylaniline (C2), and 2-iodo-4-nitroaniline (C3), were synthesized using a one-pot in situ reaction strategy without isolating the corresponding ligands. The complexes were characterized using standard spectroscopic techniques, and the solid-state structures for C1 and C2 were determined by a single-crystal X-ray diffraction analysis. The Schiff base-derived complexes (C1, C2, and C3) were fabricated as an electrode material, and their electrochemical performance was evaluated in a 2 M KOH aqueous electrolyte. Cyclic voltammetry confirmed their pseudocapacitive behavior, as evidenced by distinct redox peaks. Among the three elect
