Halogen Bonding to Carbon: a Directional Interaction for the Reliable Design of Supramolecular Architectures Based on Non-derivatized Aromatic Carbon Systems
Abstract:Carbon, although the central element in organic chemistry has been traditionally neglected as a target for directional supramolecular interactions. The design of supramolecular structures involving carbon-rich molecules, such as arenes, has almost exclusively been limited to π-stacking of aromatic systems, or derivatization with heteroatoms as sites for molecular recognition. Here, we demonstrate that C-I···Cπ halogen bonds to carbon-based π-systems can be reliably used as direction-al interactions for the cre… Show more
