Spectroscopic Studies Of Fluoranthene And 3-Nitrofluoranthene, Matthew Parks Mar 2009

Spectroscopic Studies Of Fluoranthene And 3-Nitrofluoranthene, Matthew Parks

Undergraduate Research Conference

Polycyclic aromatic hydrocarbons (PAHs) are known byproducts of anthropogenic sources including incomplete combustion of fossil fuels. They are known to be teratogenic, mutagenic and carcinogenic. This study investigated the spectral properties of fluoranthene and 3- nitrofluoranthene using NMR, UV-Vis and infrared techniques. The acquisition of spectral data provides a means to identify these compounds in mixtures and can be used which to develop model formulae for quantitation. A 2-D NMR method (HMQC ) was used for assigning 13C peaks. The infrared spectrum for 3-nitrofluoranthene showed characteristic strong absorption peaks at 1323 and 1516 cm-1 assigned to symmetric/asymmetric nitro stretches, respectively. …


Singlet Oxygen Delivery Through The Porous Cap Of A Hollow-Core Fiber Optic Device, Matibur Zamadar, David Aebisher, Alexander Greer Jan 2009

Singlet Oxygen Delivery Through The Porous Cap Of A Hollow-Core Fiber Optic Device, Matibur Zamadar, David Aebisher, Alexander Greer

Faculty Publications

The development of the first photosensitizer/fiber optic device is reported. An oxygen-flowing, fiber-capped configuration is used for the application of heterogeneous, spatially confined singlet oxygen delivery in aqueous media. This is a unique device, unlike other heterogeneous photosensitizers, in which local concentrations of singlet oxygen can be delivered via introduction and withdrawal of the fiber tip.
