Material Scale-Up to Support Synthetic and Fundamental Photophysical and Structural Studies for Advanced Organic Photovoltaics.

Abstract

1. The Marder group will synthesize key intermediates on the scale of hundreds of grams, (i) to facilitate the large-scale synthesis of established active materials (see below) and (ii) to providebuilding blocks to the MURI synthetic groups for the development of new active materials;2. A first target will be the rigid indacenedithiophene (IDT) molecules and intermediates that arecritical constituents in small molecules and polymers that have shown relatively highcharge mobility and have demonstrated both donor and acceptor behavior in relativelyhighly efficient OPVs;3. A second target will be modern high-performance OPV polymers in multi-gram quantities including ~PCE-11~ (a polymer containing the difluorobenzothiadiazole moiety), in some cases utilizing C-H activation chemistry that we have developed in other programs to reduce synthetic steps, hazards, and chemical waste; and 4. The above-mentioned intermediates, polymers, donors, and acceptors will be purified and chemically characterized and made available to Center and ONR collaborators;5. In consultation with the MURI team, additional key materials will be identified and scaled up.
