Abstract

Detailed structural organization in organic films are investigated using grazing incidence X-ray scattering (GIXS) methods. The key structural features are revealed and the influence of specific side chain positions and shapes are characterized. A correlation between the fill factor (FF) of the corresponding device and the tightness of the polymer chain stacking inspires a new set of structural parameters for design of materials to optimize device efficiency.
