Understanding Assembly Pathways of Conjugated Polymers: Synthetic Strategies for Controlling Aggreg
Abstract
The Georgia Institute of Technology proposes a research program, to be carried out in strong collaboration with groups at the Univer,sity of Arizona, University of Illinois Urbana-Champaign, and Purdue University. We seek to advance our understanding of how to opt,imize the solid-state and redox properties of conjugated polymers (CPs) by controlling aggregation in the processing solution, and h,ow assembly processes occur in solution and as they form thin films. We will explore how the nature of the polymer aggregates and as,semblies affects redox doping, charge carrier generation and transport, as well as polymer-solvent, polymer-dopant, and polymer-mole,cular additive (e.g., non-fullerene acceptors and chiral molecules) interactions. Our approach is to design and synthesize high perf,ormance materials, where side chains control aggregation and assembly, and where the backbone conjugation is varied to manipulate in,termolecular packing and ordering. Collaborations in electronic structure calculations and molecular dynamics simulations (Jean-LucB,rdas), processing and aggregate/film structures (Ying Diao), and doping to high and stable conductivities (Jianguo Mei), will provi,de scientific breadth to the program. The results will aid in the design of materials, and the determination of processing condition,s, for providing films of high electrical conductivity, redox activity for switchable devices (e.g., conducting elements, electromag,netic absorption), and mobile power generation addressing multiple Navy needs.Approved for public releaseThe Georgia Institute of Te,chnology proposes a research program, to be carried out in strong collaboration with groups at the University of Arizona, University, of Illinois Urbana-Champaign, and Purdue University.
