“…The 1 H NMR analysis of the 74-Hg 2+ complex showed that the ion interacts with the nitrogen atoms in 1H-pyrazoline and 2-benzothiazole. This finding is supported by theoretical computations conducted using density functional theory [96].…”

“…The interaction of 74 and 75 with various metal ions was systematically studied in acetonitrile using cyclic voltammetry and differential pulse voltammetry [96]. The addition of Hg 2+ ions to this solution produces the appearance of a new process at 0.078 and 0.100 V more positive potentials with the consequent disappearance of the process related to the free 74 and 75 receptors, respectively.…”

This study investigates novel ferrocene-based electrochemical sensors for metal cation detection via the design, synthesis and characterisation of ferrocene derivatives. Specifically, this research determines the redox potentials of ferrocene versus decamethylferrocene to provide insight into the redox potential variations. The investigation also examines how electrochemical oxidation of the ferrocene moiety can modulate host affinity for transition metal cations via effects such as electrostatic interactions and changes to coordination chemistry. Metal ion coordination to receptors containing functional groups like imine and quinoline is explored to elucidate selectivity mechanisms. These findings advance the fundamental understanding of ferrocene electrochemistry and host–guest interactions, supporting the development of improved cation sensors with optimised recognition properties, sensitivity and selectivity. Overall, this work lays the necessary groundwork for applications in analytical chemistry and sensor technologies via customised ferrocene-derived materials.

“…The enormous number of nitrogen containing heterocyclic compounds have been under continuous investigations from different points of view and found applications in pharmaceutical research and drug discovery. Among the nitrogen containing heterocycles, pyrazolines are five‐membered heterocyclic compounds containing two nitrogen atoms that signify a vital scaffold for various bioactive compounds with diverse pharmacological activities like anti‐oxidant [2], anti‐cancer [3], anti‐bacterial [4], antifungal [4], anti‐viral [5], anti‐inflammatory [6], anti‐tubercular [3a], immunosuppressive [7], antitumor [8], antiparasitic [8], antidiabetic [8], and analgesic [9], used as recognition of transition metal ions [10], brightening agents in synthetic fibers [11], fluorescent probes in chemo‐sensors [12], and electrophotography and electroluminescence [13]. Several reports show that the pyrazoline derivatives have a significant inhibitory effect toward the monoamine oxidase enzymes (MAOs), which are known to be responsible for neurodegenerative disorders [14].…”

The new series of various N-substituted pyrazoline derivatives containing benzo [b]thiophene and styryl with trifluoromethyl substitution at meta-posi-) was further substituted with various thiols. The structures of newly synthesized compounds were characterized by UV, IR, NMR, and Mass and had been screened for antioxidant and antimicrobial activity. The in vitro antioxidant screening revealed that hydroxyl radical scavenging (HRS) activities of compounds 3a, 3b, 3c, 3f, 3i, 3j, 4a, and 4c are stronger than the other compounds and the in vitro antimicrobial activities of the compounds were tested against Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Bacillus subtilis, Staphylococcus aureus, Enterococcus faecalis, Aspergillus flavus, and Aspergillus Niger. The compounds 3d and 3e exhibit good activity against P. mirabilis. Compounds 3a, 3b, 3c, 3 h, 3i, 3j, and 4a showed significant activity against S. aureus. Compounds 3e and 3f showed very good activity against A. flavus. Compounds 3e, 3f, and 4c showed good activity against A. Niger.

This article describes the synthesis, optoelectronic properties and anti‐inflammatory activities of a series of seven ferrocenyl ester‐linked 4‐arylidene‐5‐imidazolinone conjugates. Three different types of ortho‐, meta‐ and para‐substituted ferrocenyl esters have been prepared. Their UV–Vis spectra and electrochemical studies are described. The structure of one of the conjugates was confirmed by single‐crystal X‐ray diffraction study. These conjugates exhibited moderate anti‐inflammatory activities.
