    • 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 ...

    • Reduction Data Obtained from Cyclic Voltammetry of Benzophenones and Copper-2-Hydroxyphenone Complexes 

      Chiyindiko, Emmie; Langner, Ernst H. G.; Conradie, Jeanet (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-19)
      This article provides detailed redox data on nine differently substituted benzophenones and ten square planar copper(II) complexes containing 2-hydroxyphenones obtained by cyclic voltammetry (CV) experiments. The information provided is related to the published full research articles “An electrochemical and computational chemistry study of substituted benzophenones” (Electrochim. Acta 2021, 373, ...

    • Spectroscopic Behaviour of Copper(II) Complexes Containing 2-Hydroxyphenones 

      Chiyindiko, Emmie; Langner, Ernst H. G.; Conradie, Jeanet (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-16)
      Theoretical investigations by density functional theory (DFT) and time-dependent DFT (TD-DFT) methods shed light on how the type of ligand or attached groups influence the electronic structure, absorption spectrum, electron excitation, and intramolecular and interfacial electron transfer of the Cu(II) complexes under study. The findings provide new insight into the designing and screening of ...
