研究领域

The Wasielewski group is addressing key problems at the core of Solar Energy Science and Quantum Information Science. We work at the interface of physical and organic chemistry to explore topics such as coherent dynamics of multi-spin qubit systems, mechanisms of photodriven charge and energy transfer, and solar-to-chemical fuel production. Our research is enabled by our broad collective expertise in chemical synthesis, time-resolved laser spectroscopy/microscopy, and magnetic resonance. Solar Energy Research Producing electricity directly from sun light using organic photovoltaics (OPVs) is an important step away from fossil fuel energy sources. Our work focuses on improving key fundamental processes in OPVs. To this end, we design and synthesize covalently bound electron donor-acceptor molecules which 1) strongly absorb solar radiation, 2) efficiently separate charges intramolecularly, 3) readily assemble to form charge transport conduits. Quantum Information Science We are exploring the coherent dynamics of multi-spin systems for quantum computing, communications, and sensing applications. Different flavors of photo-initiated chemical reactions allow us to generate spin systems with a well-defined initial configuration, crucial for quantum information processing. We study, manipulate, and control these coherent spin states with techniques including transient absorption (TA) spectroscopy, time-resolved electron paramagnetic resonance (TREPR), pulsed electron magnetic resonance (pulsed-EPR), and optically detected magnetic resonance (ODMR) spectroscopies.
