The effect of alkyl side chain addition on the intermolecular vibrational modes in high charge carrier mobility molecular semiconductors

Abstract: Carbon based organic semiconductors offer the ability to create advanced electronics with materials that can be processed from solution through low cost and high volume methodologies such as printing. However, because these molecules are held together by weak forces, they can undergo intermolecular vibrations. These vibrations are thought to modulate the electronic coupling between molecules and therefore localise charges on single units on very short time scales, reducing the effective mobility. To date, little work has been done in understanding how molecular design can be used to suppress these vibrations and therefore boost the charge carrier mobility. Our group has previously theoretically identified long axis alkyl chain addition as a methodology to suppress these modes. Therefore, our proposal aims to quantify this effect in two classes of top performing organic semiconductors.
