Thin films made out of conjugated small molecules and polymers exhibit very interesting semiconducting properties. While some applications such as light emitting diodes (OLED) are already on the market, other application such as solar cells, integrated circuits, and sensors are still a topic of research. Here, the challenge is to explore experimentally the relation between structural and electronical properties. I will highlight the different contributions that x-ray techniques (reflectometry, grazing incidence diffraction, off-specular scattering, crystal truncation rod scattering) provided in the analysis of structural details of such organic thin films. Examples include transistors, solar cells, and sensors based on organic electronics materials.
