Halogen Bonding Mediated Hierarchical Supramolecular Chirality

As a highly directional force, halogen bonds based on σ-holes have potential to manipulate supramolecular chirality and build functional chiral systems, which however are largely unexplored. In this work, we report the manipulation of supramolecular chirality in hierarchically self-assembled systems via intracomponent halogen bonds. Cholesteryl cyanostilbene conjugates and 1,3,5-trifluoro-2,4,6-triiodobenzene formed a C3 symmetrical...
