Impactful advances in catalysis, medicine, and energy applications can be accessed through control of materials morphology on the nanometer size scale.  Specifically, great improvements in the power conversion efficiency of plastic-based solar cells are expected if alternating, parallel nanoscale domains of p-type and n-type materials span two electrodes.  To access this morphology, conjugated polymers can undergo solution-based self assembly to give crystalline fibrillar nanowires which serve as templates for the organization of n-type particles and small molecules, ultimately giving alternating nanoscale domains of the p-type polymer and n-type particle. This presentation will describe the solution crystallization of the archetypical conjugated polymer, poly(3-hexyl thiophene) (P3HT), into functional nanowires and the subsequent functionalization and assembly with n-type materials. The solution-based crystallization of low band gap polymers will also be addressed.
