Non-aggregating Poly(p-benzamide)s

Controlling Molecular Self-Assembly on an Insulating Surface by Rationally Designing an Efficient Anchor Functionality That Maintains Structural Flexibility

“…Due to their inherently extended chain structure 15 and their ability to form hydrogen bonds between chains, 16À18 shape-persistent oligo(pbenzamide)s are promising candidates for use as supramolecular building blocks and the creation of molecular rods. 18 The building block is specially designed to allow for electrostatic interaction of iodine atoms with the surface calcium ions, thus ensuring a strong and site-specific anchoring. At the same time, the iodine atoms do not significantly interfere with the intermolecular interaction that is encoded in the functional groups attached to the molecular core.…”

“…Here, we present a linking strategy based on the development of a versatile molecule from the class of shape-persistent oligo( p -benzamide)s that provides stable and site-specific anchoring of the molecular building block toward the surface of a bulk insulator, namely, calcite(10.4). Due to their inherently extended chain structure and their ability to form hydrogen bonds between chains, − shape-persistent oligo( p -benzamide)s are promising candidates for use as supramolecular building blocks and the creation of molecular rods . The building block is specially designed to allow for electrostatic interaction of iodine atoms with the surface calcium ions, thus ensuring a strong and site-specific anchoring.…”
