CERBERUS-TYPE TRISANIONIC TRISNHC AND ITS ZWITTERIONIC GOLD AND SILVER COMPLEXES
… systems. The resulting zwitterionic metal complexes of type [(MPPh)<sub>3</sub>(NHC)] (M = Au or Ag) have been fully characterized by spectroscopic techniques, as well as elemental analysis. To our knowledge, this NHC is the first trisanionic Cerberus-type NHC to be synthesized and …

Toward the Synthesis of Trianionic Cerberus-Type N-Heterocyclic Carbenes and their Zwitterionic Gold and Silver Complexes
… and its corresponding transition metal complexes. The free carbene was generated in situ by deprotonation of the corresponding zwitterionic salt with KHMDS. The free carbene was characterized by <sup>1</sup>H and <sup>13</sup>C NMR spectroscopy. The corresponding thione was obtained by …

Synthesis and evaluation of selected benzimidazole derivatives as potential antimicrobial agents. An investigation into the synthesis of substituted benzimidazoles and their evaluation in vitro for antimicrobial activity.
… and fungi. In addition, six bezimidazole silver complexes were prepared and evaluated for their antimicrobial behavior. The SAR showed that the antimicrobial activity of the compounds depended on the substituents attached to the bicyclic heterocycle. Some promising results were obtained. …

Synthesis and charaterisation of phosphorescent copper (I) complexes for light emitting devices
… technology is focused on organo-transition metal complexes, which emit from the triplet excited state and exhibit bright phosphorescence. Efficient in devices have been reported using these luminescent materials, such as iridium and platinum complexes, however, rare metal abundance concerns, high …

Coinage metal complexes bearing mono-supported borohydride ligands based on scorpionate scaffolds
… a singly supported borohydride ligand to copper complexes in Chapter 3. The ligands utilised were based on known scorpionate scaffolds and were compared to their bis- and tris- counterparts. The coordination of the mono- ligands allows for the [BHn]− unit to come into closer proximity to the …
