Abstract
The design of molecules and polymers for solution-deposited organic semiconducting materials generally considers the chemical modulation of (i) the π-conjugated backbone to modify the electronic and optical characteristics and (ii) the alkyl side chains to govern solubility. As the solid-state material forms, physical interactions among these constituents play an important, yet not well understood, role in directing the molecular-scale packing arrangements that in part determine the final material properties. In this presentation we will discuss how the dynamics of these moieties under different conditions, including the potential for conformational disorder among various points of torsion within the π-conjugated backbone, can impact aggregate formation and resulting solid-state morphology. The chemical insight developed through these investigations is beginning to refine and offer novel understanding essential to the development of next generation organic semiconducting active layers.
