Özet
In this study, a novel NO-type Schiff base ligand (LH) was synthesized via the condensation reaction of 4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)aniline and 2-hydroxy-1-naphthaldehyde, followed by the preparation of its corresponding Ni(II)complex. The structures of the ligand and its metal complex were comprehensively characterized by elemental analysis,1H NMR, FT-IR, UV-Vis spectroscopy, cyclic voltammetry (CV), thermal analysis (TGA/DTA), scanning electron micros-copy (SEM), and magnetic measurements. Spectroscopic and magnetic results indicate that the Ni(II) complex adopts afour-coordinated distorted geometry with an ML(2)stoichiometry. Electrochemical investigations reveal that the redoxbehavior is governed by the conjugated SNS backbone and the imine functionality, confirming the donor-acceptor natureof the system. SEM analysis demonstrates a heterogeneous and porous morphology, which is favorable for ion diffusionand charge transport. Furthermore, metal coordination leads to a decrease in the electrochemical band gap, confirmingenhanced charge delocalization and improved electronic properties. These results establish a clear correlation betweencoordination-induced electronic modulation and electrochemical behavior. In addition, the incorporation of heteroatoms(N, O, and S) within the ligand framework highlights the relevance of main group elements in tuning coordination andelectronic properties. Overall, this study provides valuable insights into SNS-based Schiff base systems and demonstratestheir potential for electrochemical and optoelectronic applications.
