Abstract
Whereas products of thermal reactions are thermodynamically more stable than the reactants, products of photoreactions can be thermodynamically less stable than the starting materials. Presented in my talk will be photon-promoted synthesis where chemical bonds and/or entities are activated and are reacted with the aid of a photon. Our fundamental strategy consists of two phases. The first phase is a photo-induced endergonic process. A photon donates energy to the reactant to produce a more energetic intermediate. The second phase is a thermal process converting the energetic intermediate to a desired product. The energy gained in the first phase provides the driving force required for the second phase. The net transformation can be energetically uphill, which is impossible with thermo-driven transformations.
