• Applications of inherently chiral calix[4]arenes 

      Van Laeren, Laura Jane (Stellenbosch : Stellenbosch University, 2013-03)
      ENGLISH ABSTRACT: Calixarenes are large cyclic molecules that have a distinctive bowl-shaped geometry. The nonplanar nature of these molecules means that, by selectively functionalizing the calixarene on one side of the ...
    • Selective distal functionalization of resorcinarenes via an ortholithiation approach 

      Ngodwana, Lonwabo (Stellenbosch : Stellenbosch University, 2012-12)
      ENGLISH ABSTRACT: Resorcinarenes are tetramers, belonging to a class of [1]4metacyclophanes, easily formed by the acid- or base-catalysed condensation of resorcinol and aldehydes. Properties include, amongst others; bowl-like ...
    • Studies in the selective synthesis of bidentate resorcinarene ligands 

      Kleinhans, Dewald Johannes (Stellenbosch : University of Stellenbosch, 2010-03)
      ENGLISH ABSTRACT: Resorcinarenes are macrocyclic products formed from the condensation of aldehydes (aliphatic or aromatic) and resorcinol and have been used in a wide range of applications since their first synthesis. ...
    • A study towards the synthesis of dithiadiazolyl functionalised calix[4]arenes 

      Applewhite, Malcolm (Stellenbosch : Stellenbosch University, 2012-03)
      ENGLISH ABSTRACT: Dithiadiazolyl heterocyclic radicals form part of an ever-growing research field in the quest for organic magnets and conducting materials due to the lone electron located within the heterocyclic ring. ...
    • Synthesis of distally substituted thioether resorcinarene ligands 

      Bhana, Ashlyn (Stellenbosch : Stellenbosch University, 2017-12)
      ENGLISH ABSTRACT: In this thesis it is reported the attempts to synthesise a series of distal thioether functionalised resorcinarene ligands. Chapter 1 provides an overview in order to familiarize the reader about the ...
    • Towards light switchable surfaces 

      Reader, Paul (Stellenbosch : Stellenbosch University, 2011-12)
      ENGLISH ABSTRACT: Polymeric nanofibrous membranes that act as surfaces offer two compelling properties; they have extremely large surface areas that can be modified and they can offer multiple reactive sites depending on ...
