Two of them whose center metal ions are zinc and nickel were selected to study their solution behaviors. The solution behaviors of water-soluble cube like polyoxopalladates by titrating small counter-cations were investigated by laser light scattering. The self-assembly behavior of the polyoxopalladates into the “blackberry” supramolecular structures induced by adding barium counter-cations was observed. Moreover, transmission electron microscopy (TEM) experiments were carried out to further prove the hollow spherical, vesicle like, self-assembled structures. Isothermal titration calorimetry (ITC) experiments were carried out to study the interaction between different counter-cations and polyoxopalladates. Finally, the small polyoxopalladate macroions are also good models to investigate the size limit of the self-recognition behavior of polyoxometallates. 2015-05-27 English text University of Akron / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=akron1427998191 http://rave.ohiolink.edu/etdc/view?acc_num=akron1427998191 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
