“…A hypsochromic shift from 748 to 680 nm was encountered, and new bands at 510, 581, and 854 nm were observed during this process. Metal-based reduction [49] and formation of [Cl 1− -Mn II Pc −2 ] 1− species are consistent with these spectral changes. When this process was completed, [Cl 1− -Mn II Pc −2 ] 1− species underwent a release of the axially bound chloride ion and a new species, namely [Mn II Pc −2 ], was formed.…”

We report the synthesis of non-peripheral metallophthalocyanines which carry four 4-(4-methoxyphenyl)-2-thiazole-2-thio units. 1 H-NMR, FT-IR, UV-Vis, and MS data were acquired to characterize the synthesized compounds. Voltammetric and in situ spectroelectrochemical measurements shed light on the redox properties of the metallophthalocyanines (MPcs) in order to show the influence of the metal cations and thiazole-bearing substituents. In solution, the redox processes had an influence to the electrochromic responses, which were examined with in situ spectrocolorimetry. Phthalocyanines having cobalt (II), manganese (III), iron (III), and zinc (II) at the center yielded characteristic redox couples which are metal-and/ or Pc-based and which are harmonious with the common redox properties of these types of compounds. In situ spectroelectrochemistry provided the information that MPc species underwent distinct color changes during electron transfer reactions. Electropolymerization of all complexes was performed on glassy carbon electrode, and the electropolymerized film of FePc was evaluated as an active electrocatalyst, in the alkaline medium, for oxygen evolution reaction (OER).

“…For instance, Özkütük et al reported the irreversible oxidation wave of six different thiazole ligands at around 1.0 V vs Ag/AgCl in DMSO/TBATFB electrolyte [33] . The studies indicate that the redox mechanisms of similar ligands could be easily modified with substitution and upon coordination [36][37][38][39] . Herein, the voltammetric results suggest that coordination of the TH ligands does not influence the redox responses of the ligands due to the redox inactivity of Zn(II).…”

“…[75] Studies also indicate that the redox features of these ligands can be tailored by the coordination of the ligands to various metal cations. [76][77][78][79] In the present study, we have examined the influence of the coordination of pyridil-based THs to Cd 2+ cation, as well as the influence of the electrolyte to the redox responses of 1 and 2. Voltammetric and in situ UV-Vis spectroelectrochemical characterizations of 1 and 2 in DCM/TBAP and DMSO/TBAP electrolytes on GCE were performed.…”

Interest in Cd complexes has been growing in recent years. Cd complexes are considered a potential solution in the search for novel antibiotics that can fight antimicrobial resistance. In addition, Cd complexes draw attention to material chemistry. The main objective of this work was to prepare the first Cd(II) complexes with anionic forms of pyridine‐based thiazolyl hydrazone (THs) ligands HLS2 [(E)‐4‐(4‐methoxyphenyl)‐2‐(2‐[pyridine‐2‐ylmethylene]hydrazinyl)thiazole] and HLS3 [(E)‐2‐(2‐[pyridine‐2‐ylmethylene]hydrazinyl)‐4‐(p‐tolyl)thiazole] and perform their structural and spectroscopic characterization, as well as stability in solution and upon heating. Studies related to their biological activities and possible electrochromic applications are also being conducted. Complexes [Cd(HLS2)2] (1) and [Cd(HLS3)2] (2) have been characterized by a single‐crystal X‐ray diffraction and computational analysis of intermolecular interactions responsible for their solid‐state structures was performed. Thermal stability of 1 and 2 in the solid‐state was analyzed by TGA/MS, where as their solution stability was determined by the spectrophotometric titration method. Electrochemical and in situ UV–Vis spectroelectrochemical analyses of 1 and 2 were carried out to determine redox mechanisms and the influence of the substituents and electrolytes on their redox responses. The antioxidant capacity of both complexes was tested in antioxidant assays, while their antimicrobial activity was tested against five Gram‐positive and four Gram‐negative bacteria, as well as against three fungi. The obtained results indicate their potent antioxidant capacity. The antimicrobial activity of investigated compounds on almost all tested bacterial strains was stronger than that of the standard antibiotic erythromycin. The results of docking studies indicate that the minor groove DNA is the possible biological target of 1 and 2.
