Abstract Details

2006, Doctor of Philosophy, University of Akron, Polymer Science.
A series of metallomacrocycles employing functionalized bis(terpyridine) building blocks were designed and constructed by both self-assembly and step-wise procedures. Based on terpyrine-metal(II)-terpyridine connectivity, application oriented metallomacrocycles possessing controlled ligand juxtapositioning (i.e., 60°, 109°, 120° angles) led to the ability to form trigonal, pentagonal, and hexagonal shape-persistance macrocycles, respectively. Angular control units consisted of benzene, triphenylamine and carbazole moieties. Transisition metals [Ru(II), Fe(II), and Zn(II)] were used as the glue to bind together the terpyridine ligands. All the intermediates and final products were characterized by means of 1H NMR, 13C NMR, UV/Vis, and mass techniques. Using a simple cation exchange reaction, I have built a multi-walled carbon nanotube (MWNT) nanocomposite that was confirmed by Transmission Electron Microscope (TEM) and Energy Dispersive X-ray Spectroscopy (EDXS) analysis to extend our modular chemistry. Studies of photoelectrochemical and luminescence properties have shown these metallomacrocycles to be useful for fabricating molecular devices such as dye-sensitized solar cells and organic light-emitting diodes.
