Synthesis And Self-Assembly Of V-Shaped Amphiphilic Oligomer Moleculars

The properties of functional nanomaterials are frequently enhanced when they have a well-organized internal structure and,as a consequence,molecularly organized supramolecular materials are promising candidates for applications in the field of supramolecular chemistry,so the supramolecular architectures formed by the self-assembly of block molecules have received great attention.Among the polymer scaffolds,amphiphilic block copolymers consisting of hydrophobic and hydrophilic blocks,can self-assemble into various core-shell nanoaggregates.These aggregates incorporate a specific shaped rod block and control the interaction force between molecules with desired functions,and act as novel functional nanomaterials.Thus,they have remarkable potential in fields such as biochemistry,molecular electronics,biomimetic chemistry,and materials science.This thesis designed and synthesized linear shaped,V-shaped molecular isomers and incorporation of methyl group of the rod centre with the V-shaped block oligomers.The self-assembling behavior of these molecules in bulk and in aqueous solution was investigated by'H-NMR,TOF-MASS,DSC,POM,SAXS,UV-vis and FL spectroscopy,CD,DLS,AFM and TEM.Mainly discuss the influence of rigid shape?flexible chain length?flexible clain block volume fraction on the self-assembly behaviors in bulk and in aqueous solution.
