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 …

Synthesis And Characterization Of Manganese Pyridazyl Complexes, Sana Shah
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 …

Synthesis Of Rhenium And Manganese Pyridazoal Complexes, Jesse Evans
Masters Theses & Specialist Projects
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 …

Mahurin Honors College Capstone Experience/Thesis Projects
Heterocyclic organic and organometallic compounds (e.g. polypyrrole, Figure 1A) and their derivatives have been of great interest for conductive polymers due to their novel properties, such as their versatile structure and ease of synthesis. In addition, these molecules have a great environmental stability compared to non-aromatic analogs (e.g. polyacetylene, Figure 1B). We have been interested in synthesizing organometallic pyridazyl (Figure 1C) complexes for polymer research. Figure 1. Structures of A–D. Pyridazyl complexes of rhenium were synthesized in three steps beginning from 1,2-diacylcyclopentadienes (aka, fulvenes, Figure 1D). Synthesis, characterization and molecular structure of [Mn(CO)3{1,2-C5H3(CC4H3ON)(CC4H3ON)}] (4A), [Re(CO)3{1,2-C5H3(CC4H3ON)(CC4H3ON)}] (4B), and their precursors are …

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 …
