Donor-Acceptor Superstructures with Emergent Optoelectronic Properties: Synergistic Approaches to Functional Self-Assembling Aggregates
Abstract
To create synthetic materials with optoelectronic properties two fundamental challenges must be overcome, namely, understanding how multicomponent supramolecular systems assemble into mesoscale structures, and determining how novel optical and electronic properties can emerge by bringing together donor and acceptor components that individually lack the desired properties. Herein we describe the design, preparation, and study of a novel self-assembling system composed of diketopyrrolopyrrole (DPP) electron donors and perylene diimide (PDI) electron acceptors, where multiple, complementary noncovalent interactions direct the assembly of hierarchical superstructures that will undergo efficient charge generation and long-distance charge separation in solution and the solid-state. Specifically, we describe: (1) The assembly of DPP-PDI superstructures in solution and in the solid-state to develop new predictive models that quantitatively explain heteroaggregation with different components, donor-acceptor ratios, and environmental conditions, (2) an understanding how structure and FMO energies interact to produce emergent properties that respond external stimuli, and (3) the production stable solid-state materials that can be incorporated into electronic devices.
