    • DFT and electrochemical study on some iron(III) complexes with 2-hydroxybenzophenones 

      Chiyindiko, Emmie; Langner, Ernst H.G.; Conradie, Jeanet (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-17)
      The synthesis, identification and electrochemical behaviour iron(III) complexes containing different 2-hydroxybenzophenone ligands are reported. The first reduction of the tris(2-hydroxybenzophenone)iron(III) complexes follow the same trend as that of the free, uncoordinated ligands and bis(2-hydroxybenzophenone)copper(II) complexes. The first reduction of the iron(III) complexes occur at a potential ...

    • Electrochemical behaviour of 2-hydroxybenzophenones and related molecules 

      Chiyindiko, Emmie; Langner, Ernst H.G.; Conradie, Jeanet (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-23)
      An electrochemical study, using cyclic voltammetry of 2-hydroxybenzophenone and related molecules, containing various electron withdrawing and/or electron donating groups, is presented. The CV profiles of the various molecules show one sharp reduction and one small oxidation wave, coupled to the reduction wave. Density functional theory (DFT) calculations shed light on the transmission of charges ...
