Abstract
A new supramolecular system based on halogen-bonded macromolecular substances is presented. Binding and complex formation between a halogen bond acceptor N-benzyl ammonium resorcinarene bromide and a library of polymeric halogen bond donors based on iodotetrafluorophenoxy functionality is shown. The complex formation was confirmed in liquid state by dynamic light scattering and transmission electron microscopy. Spectroscopic measurements in the solid state verify the halogen bonding. In particular, the study shows that both homopolymers and polyethylene glycol block copolymers act as effective halogen bond donors leading to polymer-architecture-dependent complex morphologies.
