Abstract Details

2019, Doctor of Philosophy, University of Akron, Polymer Science.
Macroions with sizes between 1 and 10 nm show interesting and unique solution behavior in the way of interacting with counter-ions, co-ions, and solvent molecules. They do not follow Debye-Huckel or DLVO theory. With modest charge density, many of them could spontaneously self-assemble into single-layered hollow spherical blackberry-type structures by counterion mediated attraction. The self-assembly structures can be well controlled, and their sizes correlate well with the charge density of macroions. The charge density of macroions is tunable through the alternation in solvent polarity, addition of electrolytes and other approaches. Therefore, exploring the self-assembly process could be an efficient method to understand the solution behavior of single macroions. Moreover, it is also a very powerful technique to explore the weak non-covalent interactions in the system, which affects the assembly process of macroions, but are difficult to be characterized by traditional methods. In this dissertation, various macroions, including metal-organic cages and polyoxometalates, are studied to understand (1) their self-assembly processes; (2) effects from host-guest chemistry, counterions, chemical functionality, non-covalent interaction (hydrogen bonding), and solvent molecules on the self-assembly process of macroions; (3) the inter-molecular interaction as well as the inter-molecular distance between macroions within blackberry structures; (4) conformational change in single macroions upon external stimuli, especially hydrophobic interaction.
