Title: Directional Charge Separation in Isolated Organic Semiconductor Crystalline Nanowires

Abstract

This research program was focused on development of new material platforms and analytical spectroscopy methodologies for probing inter- and intra-molecular electronic processes in conjugated nanomaterials. A detailed understanding of the connection between molecular architecture, supramolecular/polymer assembly, and optoelectronic function is critical to the improvement in polymer-based optoelectronics, yet many questions remain outstanding as to how to ‘program’ specific inter-molecular couplings via molecular structure in order to achieve desired device performance (photostability, chargeseparation and charge-transport efficiency). We combine single-molecule spectroscopy tools and new synthetic methodologies to probe intra- and inter-molecular coupling in small-molecule, oligomeric complex structures and crystalline nanoscale supramolecular assemblies in order to understand in detail, the structure-excitonic property relations and elucidate molecular design rules (distances, angles, etc) for improved performance in organic optoelectronics.
