Elucidating the influence of side chains on the self-assembly of semi-flexible mesogens.

In the development of functional materials, side chains are traditionally incorporated into the primary chemical structure to induce liquid-crystalline behavior or to enhance solubility for improved processability. However, emerging evidence suggests that side chains play a far more complex role. This study presents a case of a double helical supramolecular structure formed by star-shaped mesogens in the absence of specific interactions.
