Energies and Dynamics of New Pathways in Excited Metalloporphyrins Upon Ionization
Metalloporphyrins are found in various different organisms ranging from humans to plants. Metalloporphyrins consist of a porphyrin macrocycle with a coordinated metal atom at their center. They are part of many biological systems such as chlorophyll, vitamin B12, cytochrome P-450, and hemoglobin. Synthetic metalloporphyrins are used as commercial dyes and catalysts in the design of solar cells, molecular electronics, and supramolecular building blocks. The metalloporphyrins interaction with light plays a critical role in many systems therefore it is important to characterize the molecules interactions with light. The goal of my research project is to investigate the molecules interaction with light by studying the ionization of the ground and excited state using a femtosecond laser to conduct a pump-probe experiment. Metalloporphyrins of various metal centers and substituent groups on the porphyrin macrocycle will be studied in order to find how each variable affects the ionization process and excited state dynamics.
