Two is better than one: improved catalysis through cooperativity Suraj Patel, Gareth Rowlands School of Natural Sciences, Massey University, New Zealand The luxuries of modern society have been built off of the development of catalytic processes. Traditionally, catalysts have contained a single active site that promotes a single reaction. A better approach would have catalysts with multiple active sites that could then promote multiple reactions within a single reaction vessel. Enzymes, natures catalysts, have perfected this process, but synthetic catalysts lag behind. Herrin, we present our efforts to study gold-based photo switchable catalysts, highlighting their ability to produce different products in the presence or absence of light. The catalysts developed in this project are built from a [2.2] paracyclophane backbone, allowing precise control over the substitution patterns. Compared to other bifunctional catalysts, a [2.2] paracyclophane scaffold is the only one that reliably provides systematic control of the position of two active sites. Our scaffolds will allow us to place functionality with exquisite control, opening a pathway to new reactions and knowledge.
