We are physical chemists working on understanding and controlling light harvesting with organic semiconductors at
UC Santa Cruz

Organic semiconductors are π-conjugated organic molecules. The conjugated backbone leads to substantial delocalization of the electronic wavefunction , which in turn leads efficient light absorption, as well as transfer of electronic energy and electric charge over 10s to 100s of nanometers. Such characteristics make these materials highly promising for optoelectronic device applications. However, their electronic properties are extremely sensitive to their microstructure. Thus, in order to control light harvesting, we must understand the link between physical structure and excited-state processes. To do this, we primarily combine spectroscopy and photon scattering experiments. Click here to learn more…
