The demand for renewable energy sources is continually increasing for the sustainable health of the environment. Solar energy is a promising renewable energy source, and organic-based photovoltaics are particularly attractive due to their flexibility and tunability. Single-component organic photovoltaics incorporate both the donor and acceptor moieties into a single molecule, and have the potential to simplify device processing. The goal of this project is to identify suitable molecules for single-component active materials by understanding the charge transfer process between the donor and acceptor. Computations have identified promising configurations, and we are synthesizing the individual donor and acceptor molecules, as well as the coupled donor-acceptor dyad. The synthetic results were analyzed and confirmed using 13C and 1H nuclear magnetic resonance spectroscopy and mass spectrometry, and will be presented here.
