    • 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 ...

    • Trans–Cis Kinetic Study of Azobenzene-4,4′-dicarboxylic Acid and Aluminium and Zirconium Based Azobenzene-4,4′-dicarboxylate MOFs 

      Mogale, Refilwe; Conradie, Jeanet; Langner, Ernst H. G. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-17)
      Metal organic frameworks (MOFs) are porous hybrid crystalline materials that consist of organic linkers coordinated to metal centres. The trans–cis isomerisation kinetics of the azobenzene4,4´ -dicarboxylic acid (AZB(COOH)<sub>2</sub> ) precursor, as well as the Al<sup>3+</sup> (Al-AZB)- and Zr<sup>4+</sup> (Zr-AZB)- based MOFs with azobenzene-4,4´ -dicarboxylate linkers, are presented. The ...
