Abstract

Three novel Cd(II) metal complexes 13 have been synthesized with different derivatives of thiazoline, hydrazide and carbodithioate. These metal complexes are abbreviated as [Cd (tht)2]n, [Cd (Hpph)2]n and [Cd (mpps)2]n along with their respective ligands Htht, H2pph and mpps. The developed metal complexes are characterized using X‐ray diffraction (XRD) data and other spectroscopic techniques (Infrared [IR], nuclear magnetic resonance [NMR], ultraviolet–visible [UV–vis] and fluorescence). The polymeric nature of these cadmium complexes have been ascertained by single XRD data. Several significant interactions were also revealed, which aid in the stabilization of these complexes' supramolecular architecture. Comparing complex 2 with complexes 1 and 3, the absorption spectra of complex 2 exhibits a greater λmax. On comparing the fluorescence study of these complexes, complex 2 has a higher fluorescence than complexes 1 and 3. The cyclic voltammetry (CV) approach was employed to detect the electrochemical behaviour of these complexes, as well as the sensing of uric acid (UA) by these complexes via modified glassy carbon electrodes (GCEs). According to the conclusions received by CV study, the modified electrode containing complex 3 has admirable UA electro catalytic activity. This UA electrochemical sensing device offers a low detection limit (0.3 μM), fine linear ranges (30–1500 μM), reasonable sensitivity, and a fast reaction time.
