Towards MIP “Nano-monolith”Composite Membranes for Enantioselective Separations(Herstellung und Charakterisierung von MIP “Nano-Monolith”Komposit-Membranen für enantioselektive Trennungen)byAbdus SalamThesis submitted to the Department of Chemistry,Universität Duisburg-Essen, in partial fulfillment ofthe requirements of the degree ofDr. rer. nat.Approved by the examining committee on June 11, 2008:Chair : Prof. Dr. Thomas SchraderAdvisor : Prof. Dr. Mathias UlbrichtReviewer : Prof. Dr. Christian MayerEssen, 2008iABSTRACTA molecular imprinting procedure based on hydrogen bonding interactions between the template butoxycarbonyl-D-phenylalanine (Boc-D-PhA) and the functional monomer methacrylic acid (MAA) was used to synthesize a porous molecularly imprinted polymer (MIP) in the pores of polypropylene (PP) microfiltration and poly(ethylene terephthalate) (PET) track-etched membranes for the separation of enantiomeric mixture (Boc-DL-PhA) in solution via permselective transport through these composite membranes under diffusion (dialysis) and electrodialysis conditions. Bulk porous MIP and non-imprinted polymer (NIP; for control experiments) monoliths were synthesized to optimize the synthesis conditions and their pore morphology.
