Abstract

tThe excited state and redox properties of a new bi-functional perylene redox chromophore, 2,3-dihydro-1-azabenzo[cd]perylene (DABP), are described. Perylene has been widely used in electron donor-acceptormolecules in fields ranging from artificial photosynthesis to molecular spintronics. However, attachingmultiple redox components to perylene to carry out multi-step electron transfer reactions often produceshard to separate regioisomers, which complicate data analysis. The use of DABP provides a strategy toretain the electronic properties of perylene, yet eliminate regioisomers. Ultrafast photo-initiated single-and two-step electron transfer reactions in three linear electron donor-acceptor systems incorporatingDABP are described to illustrate its utility.
