Global climate change and renewable energy are issues that are at the forefront of
national and international debate. Finding clean, carbon-neutral sources of energy
is one of the greatest technological challenges we face in the scientific community
today. In the search for abundant, clean, and renewable energy, one obvious place
to look is the sun. Photosensitizers are molecules that absorb sunlight and use that
energy to drive a (useful) chemical reaction. Solar fuels photochemistry utilizes
photosensitizers to oxidize or reduce a catalyst, which can then go on to catalyze
fuel forming reactions, allowing solar energy to be stored as chemical energy. The
drawback of this chemistry is that a majority of photosensitizers incorporate rare
second and third row metals, whose low abundance limits their use in large-scale applications.
Our goal is therefore to develop photosensitizers using more abundant first row transition
metals such as chromium and zinc and incorporate those photosensitizers into solar
