Synthesis And Characterization Of Polycyclic Aromatic Hydrocarbon ( Pah )-Porphyrin Hybrids, Ruixiao Gao

Theses and Dissertations

Carbaporphyrins are porphyrin analogs where one or more pyrrole units are replaced with a carbocyclic ring. Benziporphyrins are porphyrin analogues with a 1,3-phenylene unit replacing one of the pyrrole subunits. Because of cross-conjugation, benziporphyrins are not aromatic species. However, protonation of benziporphyrins can afford some aromatic characteristics. Although the synthesis of many examples of monocarbaporphyrins have been successfully executed, no examples of porphyrinoids with pyrene subunits have been prepared. Pyrene-containing porphyrinoids, which have been named as pyreniporphyrins, are theoretically significant molecules that provide insights into the aromaticity and reactivity of porphyrinoid systems.

In this thesis, two projects were conducted to …

Inhibitory Effects Of Unique Sulfonamides On Leishmania Tarentolae And Potential Pathway Of Inhibition, Jade M. Katinas

Theses and Dissertations

Leishmaniasis is an endemic disease caused by the protozoan parasite Leishmania. Current treatments for the parasite are limited by cost, availability, and drug resistance as the worldwide occurrence of leishmaniasis continues to be more prevalent. Sulfonamides are a class of compounds with medicinal properties that have been used to treat bacterial and parasitic diseases via various pathways. In this study, newly synthesized, unique structural analogs of sulfonamide compounds were assessed for their impact on Leishmania cell viability and potential pathways for inhibition were evaluated. Leishmania tarentolae (ATCC Strain 30143) axenic promastigote cells were grown in BHI medium and treated with …

Solid State Synthesis And Characterization Of The Rare Earth-Free Anti-Perovskites Sr2.5-Xba0.5 Al1-Xp Xo4 F ( 0 ≤ X ≤ 0.15 ), Sr3al1-Xy Xo 4 F ( 0 ≤ X ≤ 1 ), And Sr2.5-X/2ba0.5 Al1-Xhfxo4 F ( 0 ≤ X ≤ 0.1 ) As Potential Phosphor Materials, Sean Thomas Keil

Theses and Dissertations

Typical lighting systems such as incandescent and fluorescent bulbs are common in homes but are rather inefficient compared to the newer light emitting diodes (LEDs). LED-based lamps can be constructed to generate white light by combining a red, green, and blue LED, or by using an LED light source (typically with a low wavelength) with a complimentary phosphor coating to produce white light. The latter, known as phosphor-conversion (PC) LEDs, is the primary focus of this research, looking specifically at rare earth-free options for these phosphor coatings.

Anti-perovskites are a potential lattice type for this type of conversion, in particular …
