Hierarchal Ordered Structures in Hybrid Functional Supramolecules and Macromolecules
ORAL
Abstract
To create new functional materials for advanced technologies, control over their hierarchical structure and order is vital for obtaining the desired properties. We utilized and functionalized fullerene (C$_{60})$ and polyhedral oligomeric silsesquioxane (POSS), and assembed both of these particles with polymers to form those hierarchical structures. In order to do so, we have developed a novel way of attaching C$_{60}$ and POSS onto other organic materials in a highly efficient and controlled manner via ``click'' chemistry. The structure of this assembly along with the resulting ordered structures were analyzed to determine their structure-property relationships. Examples are materials of POSS-[60]Fullerenoacetate conjugate crystals, giant surfactant of polystyrene-(carboxylic acid-functionalized polyhedral oligomeric silsesquioxane) amphiphile and porphyrin-C$_{60}$ hybrids for intra- and inter-columnar in supramolecular double cable structures.
