In organic electronics, it is critically important to understand how chemical structure influences molecular packing, carrier transport and ultimately device performance. The self-assembly properties of liquid-crystalline semiconductors offer many interesting advantages for fabricating highly ordered molecular films with interesting properties, including high carrier mobilities and good thermal stability.
This tutorial will provide a comprehensive overview of molecular self-assembly and liquid crystallinity in organic electronics. We aim to highlight the great potential for exploiting these effects in large-scale applications. We will begin by introducing the basics of liquid-crystalline small molecules and polymers, liquid-crystalline mesophases, film processing and characterization and device physics. Relevant experimental and theoretical tools for studying this class of materials will be introduced. Finally, we will survey state-of-the-art results on the application of liquid-crystalline semiconductors in high-performance organic electronics
This tutorial is aimed at experimentalists and theorists in physics, chemistry and materials science.
