Molecular (green) and unit-cell (brown) dipoles of an asymmetric organic semiconductor.

Considering the success of recently marketed consumer technology based on organic semiconductors, such as the OLED TV, it is clear that these materials have considerable potential for application in the opto-electronic devices of the future. Designing, synthesizing and characterizing new functional materials with properties tuned to match these applications remain central issues in the development of this technology. Detailed knowledge of their crystal structures is indispensible, in particular in the case of asymmetric systems which crystallize in polar space groups and display nonlinear optical activity.
