Synthesis, Structure Characterization and Biological Activity of Co (II), Cu (II), and Zn (II) Complexes with (Z)‐3‐((3‐hydroxybenzylidene)amino)pyridin‐1‐ium 4‐(dodecan‐4‐yl)benzenesulfonate Surfactant

Abstract

Z)-3-((3-hydroxybenzylidene)amino)pyridin-1-ium4-dodecylbenzenesulfonate anionic surfactant and its cobalt, copper and zinc complexes were synthesized (I, I-Co, I-Cu and I-Zn). The chemical structures of it were characterized by elemental analysis, FTIR, 1 H-NMR, UV-Vis spectroscopy and atomic adsorption. The effects of the chemical structures of the synthesized anionic surfactant and the type of transition metals on the surface activity are presented in this paper. The thermodynamic parameters show that adsorption and micellization processes are spontaneous. The results of biological activity measurements showed that the synthesized compounds have a great efficiency against gram positive (Bacillus subtilis and Staphylococcus aureus), gram-negative bacteria (Pseudomonas aeruginosa and Escherichia coli) and fungi (Candida albicans and Aspergillus niger) as well as the sulfate reducing bacteria (Desulfomonas pigra). The complexation of the anionic surfactant with Co 2? , Cu 2? and Zn 2? increase the antimicrobial activity values.

Alginate surfactant derivatives as an ecofriendly corrosion inhibitor for carbon steel in acidic environments

“…To a solution of the synthesized alginate derived cationic surfactant (AS) (0.01 mol) in ethanol (100 ml), a metal ion solution of anhydrous CoCl 2 , CuCl 2 and ZnCl 2 (0.005 mol) in ethanol (50 ml) was added separately and reuxed for 6 h. The reaction mixture was le overnight to complete the precipitation of the products. The products were ltered off and recrystallized twice from ethanol to obtain the crystalline products of the desired alginate surfactant metal complexes (AS-Co, AS-Cu and AS-Zn) in Step 4 45,46 (Fig. 1).…”

Self-Assembling Metallocomplexes of the Amphiphilic 1,4-Diazabicyclo[2.2.2]octane Derivative as a Platform for the Development of Nonplatinum Anticancer Drugs

“…The biomedical aspect of the use of metallosurfactants is also associated with an increase in the antimicrobial activity of amphiphiles upon their complexation with metals. − In this case, surfactants of both anionic and cationic nature serve as ligands. − Typically, long-chain linear or heterocyclic amines (en, triene, bipyridine, and phenanthroline), amides, and quaternary ammonium salts containing an ester fragment are used as cationic ligands, − with Co­(III), Co­(II), Cu­(II), Sn­(II), Ni­(II), La­(III), Ru­(II), and so forth serving as the metal centers.…”
