Masters Theses & Specialist Projects
This thesis introduces the idea of Band Theory and how it can be used to describe a solid-state materials ability to carry an electrical charge. Next, this thesis defines what makes a material a conductor, semiconductor, or insulator. Semiconductors are attracting interest in chemistry, as well as in the manufacturing of consumer electronics, because of their ability to carry a charge, without the risk of short-circuiting like traditional conductors.1,4 Organic semiconductors, which behave differently than traditional semiconductors, are of particular interest because they offer mechanical flexibility, lowcost, simplicity, and the ability to be manufactures at low temperatures.6 Nonorganic and organic …

Masters Theses & Specialist Projects
Heterocyclic’s and their fused-ring derivatives have been of interest for their use in electronic materials due to their ease of production, synthetic versatility, and low cost compared to traditional inorganic materials like silicon. Pyridazines have been found to be useful in catalysis gas storage, polymeric sensors and biological mimetics. When a transition-metal is fused into a synthesized pyridazine, unique properties such as conductivity and optics are allowed. In this work, synthesized pyridazine complexes will be analyzed by mass spectroscopy, elemental analysis, nuclear magnetic resonance, imaging, x-ray crystallography, and infrared spectroscopy. We are interested in synthesizing organometallic pyridazines and manganese pyridazyl …

Organometallic pyridazines and compounds derived from them have been of interest in polymer research due to their atypical environmental stability (as compared to other non-aromatic organic semiconductors) as well as their conductivity. The off-metal synthesis and characterization of several pyridazyl thallium, manganese, and rhenium complexes, beginning with fulvenes 1,2- C5H3(COHR)(COR), are reported here. The diacyl fulvenes were treated with hydrazine hydrate to ring close to pyridazines. Next, the pyridazines were converted to their respective thallium salts through treatment with thallium (I) ethoxide. Lastly, the salts were transmetallated into the respective rhenium or manganese complexes through treatment with the respective metal …

Pyridazines are a heterocyclic aromatic compound containing a characteristic N-N bond that are utilized in many fields, including medicine and electronics. It is this latter field that Dr. Snyder's research group is focused upon. Organometallic compounds are a better conducting material than the current inorganic compounds used in electronics due to better conductance of electricity, lower production cost, and the ability to be formed into thin films. With this in mind, Dr. Snyder's research group has set out to synthesize organometallic compounds for this purpose. Following procedures set forth by Snyder etc, and altered to form an off-metal route, we …

Masters Theses & Specialist Projects
Heterocyclic organic and organometallic compounds (e.g. polypyrrole) and their derivatives have been of great interest for conductive polymers due to their novel properties and environmental stability as compared to non-aromatic analogs (e.g. polyacetylene). We are interested in synthesizing organometallic pyridazines and rhenium pyridazyl complexes for polymer research. SeveraI5,6-fused ring pyridazines (1,2-CsH3(CRNH)(CRN) have been synthesized and characterized. Additionally, pyridazyl complexes of rhenium were synthesized in three steps beginning from fulvenes 1,2-CsH3(COHR)(COR). On-Metal synthesis and characterization of (Re(CO)3 {1,2- CSH3(CRN)(CRN)}] (R=C6RtOMe, C6RtCI, C4H30) and some off-metal pyridazines are reported here. Our research is focused on synthesis of a variety of 5,6- fused …

Heterocyclic organic and organometallic compounds (e.g. polypyrrole), and their derivatives, have been of great interest for conductive polymers due to their novel properties and environmental stability as compared to non-aromatic analogs (e.g. polyacetylene). Our current interests focus upon the potential role of pyridazines in next generation electronic devices that utilize organics as the semiconducting material. Pyridazines, 6-membered aromatic rings with two adjacent nitrogens, are promising candidates for a variety of materials and commercial applications. These molecular electronic materials posses several advantages over traditional inorganic semiconducting materials including lower cost of production, higher processibility, and the ability to function on flexible …
