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.
呈现了一种基于卤键的高分子物质的新型超分子体系。展示了卤键受体 N-苄基铵均苯三酚溴化物与一系列基于碘代四氟苯氧基官能团的高分子卤键供体之间的结合和配合物形成。通过动态光散射和透射电子显微镜在液态下证实了配合物的形成。固态光谱测量验证了卤键的存在。特别是，该研究表明均聚物和聚乙二醇嵌段共聚物均作为有效的卤键供体，导致聚合物结构依赖性的配合物形态。
