Özet

A novel Schiff base, 4-bromo-2-[(2-[(5-bromo-2-hydroxyphenyl)methylene]amino-5-nitrophenyl)iminomethyl]phenol (M1) was synthesized from the reaction of 5-brom-salicylaldehyde with 4-nitro-o-phenylenediamine. Schiff base-metal complex was synthesized from the reaction of 4-bromo-2-[(2-[(5-bromo-2-hydroxyphenyl)methylene]amino-5-nitrophenyl) iminomethyl] phenol (M1) with copper (II) acetate monohydrate [(CH(3)COO)(2) Cu center dot H(2)O] salt. Poly-(M1-Cu-TDP) was synthesized from the reaction of M1-Cu with 4,4'-dithiodiphenol (TDP). Poly(M1-Cu-PDP) was synthesized from the reaction of M1-Cu with 4,4'-propane-2,2-diyldiphenol (PDP). Poly(M1-Cu-HDP) was synthesized from the reaction of M1-Cu with 4,4'-(1,1,1,3,3,3-hexafluoropropane-2,2-di-yl) diphenol (HDP). The structures of the synthesized monomer and chelate polymers were confirmed by FT-IR, UV-Vis, (1)H-and (13)C-NMR, and elemental analysis. The characterization was made by TGA-DTA, DSC, size exclusion chromatography, cyclic voltammetry, and solubility tests. Also, surface morphologies of chelate polymers were investigated by scanning electron microscope. Copyright (C) 2009 John Wiley & Sons, Ltd.
