Abstract Details

2013, Doctor of Philosophy, Case Western Reserve University, Chemistry.
The light-induced relaxation pathways of various polycyclic aromatic hydrocarbon (PAH) derivatives were studied using broadband transient absorption with femtosecond (10-15 s) time resolution, steady-state Xe-lamp irradiation, UV/Vis spectroscopy and HPLC methods. Ground- and excited-state calculations were performed to help interpret the experimental results. Two types of PAH derivatives were chosen for this research: those substituted with nitro groups and those with gold(I) phosphine groups. In both families of PAH investigated the triplet state is populated in high yield following excitation by UV light. The population of the triplet states occurs ultrafast, with lifetimes in the hundreds of femtoseconds in most cases. Kinetic mechanisms explaining the excited-state dynamics and photochemistry of these molecules are proposed. The experimental findings are reinforced with ground- and excited-state calculations at the density functional level of theory.
