    Coordination polymers as heterogeneous catalysts for oxidation reactions
    (University of the Western Cape, 2014) Alarbi, Zohra; Titinchi, Salam; Abbo, Hanna
    This study describes the synthesis and characterisation of coordination polymers complexes of Cu(II) and VO(IV) with two polymeric ligands N,Nʹ -1,2-phenylene bis(5-methylenesalicylidenamine)(L1) and N,Nʹ -1,4-butylene bis(5 methylenesalicylidenamine) (L2). Ligands L1 and L2 formed by condensation of 5,5ʹ-methylene bis-(salicylaldehyde) with 1,2-phenylenediamine and 1,4-diaminobutane respectively. The ligands and the complexes were characterized by UV/Vis spectroscopy, proton and carbon nuclear magnetic resonance spectroscopy (1H and 13C-NMR), Fourier transform infrared spectroscopy (FTIR), high resolution scanning electron microscopy (SEM) and thermogravimetric Analysis (TGA)
