Reaction Dynamics of Molecular Building Blocks

Currently working on this project: Jenna Wasylenko and Tim Quincy

Techniques: Pump-Probe, Pump-Repump-Probe, 2PA

Recently, carbon-based electronics have emerged as an alternative to the silicon-based devices that are traditionally used. These new organic electronics are fabricated from molecular components which can be exploited for their small size and versatility. For example, carbon-based electronics that incorporate conductive polymers to make flexible, transparent, and lightweight materials that can be used for applications such as flexible displays and solar cells. However, the performance of these devices is limited by the properties of the molecular components. Therefore, a fundamental understanding of how chemical modification affects the ultrafast dynamics in various organic molecular building blocks is necessary to further the field of molecular electronics. The systems we are particularly interested in are based on the thiophene and azulene moieties. Our group uses one-and two-photon absorption to identify key excited electronic states, pump-probe and pump-repump-probe transient absorption to observe the evolution on the excited-state surface, and FSRS to probe the vibrational structure and dynamics of the excited states.
