The research presented herein is concerned with the chemical modification of polysulfone towards the synthesis of a hollow fibre boronic acid fixed carrier membrane system for saccharide separation. Chapter 1 firstly introduces the area of boronic acids as chemosensors, in particular for detecting saccharides. Secondly, membrane separation techniques are discussed focussing on hollow fibre membranes and their synthesis. Chapter 2 discusses the potential of boronic acid fixed carrier hollow fibre membranes for saccharide separation. Three general routes are highlighted to achieve the desired boronic acid appended polymers: electrophilic aromatic substitution, lithiation and functional monomer polymerisation. Chapter 3 describes the various attempts at achieving the target polymer via electrophilic aromatic substitution methodology. Chapter 4 describes the various attempts at achieving the target polymer via lithiation methodology. Chapter 5 investigates the ability to create functional monomers with which functional polymers can be polymerised from. Chapter 6 describes the synthesis and characterisation of the compounds discussed in chapters 3, 4 and 5.
