A fundamental understanding of the photophysics involved in solar energy capture and conversion is crucial to the development of carbon-neutral energy technologies. Taking inspiration from nature, the photosynthetic reaction center (PSRC) is often modeled by simpler versions of its elements to allow for better control over the system and for systematic tuning of the components. 3,4:9,10-perylenebis(dicarboximide) (PDI) is often used in this regard as it is stable, synthetically tunable, and has favorable redox properties.This dissertation describes the use of PDI and its derivatives to study the fundamental photophysical processes observed in PSRC such as symmetry-breaking charge separation (SB-CS), charge transfer, and self-assembly. In chapter 2, photoinduced charge transfer in a PDI based non-covalent donor-bridge-acceptor system is analyzed as a function of the bridge molecule. In chapter 3, SB-CS is studied as a function of solvent and distance in a series of tetraphenoxy-substituted PDI dimers. In chapter 4, the work of chapter 3 is built on by demonstrating that the charge generated during SB-CS can be harvested by covalently attaching a hole acceptor molecule. In chapter 5, the use of the PDI radical anion as a super-reductant that could be incorporated into an artificial photosynthetic system is investigated. In chapter 6, the packing morphology across a series of substituted PDIs and different substrates is examined as a function of the PDI substituents and substrate surface chemistry.The molecules described herein offer increased fundamental understanding of SB-CS and other photophysical processes. This insight has great potential to aid in the development and advancement of organic electronics for solar energy capture and conversion.
