Nanomaterials synthesis has advanced rapidly over the past several decades, for the most part overshadowing similar strides in the synthesis of atomically precise clusters. A large bank of different clusters, with variations in stabilizing ligands, the choice of metal or alloy, and/or the number of metal atoms, have been isolated. The synthesis of clusters still presents challenges to even strong synthetic chemists. We have developed a photochemical method for the synthesizing Au25SR18 clusters that provides some synthetic advantages, and an opportunity to isolate new clusters.<br/>The unique optical properties of clusters will also be highlighted in this seminar, especially as they relate to the structure function-function relationship in photonic devices. The distinctive properties of individual clusters have made them attractive candidates for biomedical imaging, catalysis, photonic devices, and light harvesting. The incorporation of atomically precise clusters in photovoltaic devices will be discussed in detail, as well as the use of photovoltaics to help elucidate some of the properties of clusters that are fundamental to their use in light harvesting and other applications as well.
