摘要

主客体相互作用已被越来越多地探索用于聚合物前体的动态物理交联以形成水凝胶网络。然而,客体基序的取向受到大分子偶联的限制。这种限制对由此产生的主-客体超分子交联的动力学和热力学的影响尚不清楚。在此,来自受控区域异构体的客体交联基序被证明产生不同的材料特性。此外,潜在的现象指出了模块化客体拓扑在分子尺度上对超分子复合物形成的亲和力和动力学的进一步意想不到的影响。

Impact of Guest Orientation in Host–Guest Supramolecular Hydrogels
Host–guest interactions have been increasingly explored for use in the dynamic physical cross-linking of polymeric precursors to form hydrogel networks. However, the orientation of guest motifs is restricted upon macromolecule conjugation. The implications of such restriction on both the kinetics and thermodynamics of the resulting host–guest supramolecular cross-links are poorly understood. Herein, guest cross-linking motifs from controlled regioisomers are demonstrated to yield distinct material properties. Moreover, the underlying phenomena point to a further unexpected impact of modular guest topology on the molecular scale in both the affinity and dynamics of supramolecular complex formation.

期刊介绍: ACS Macro Letters publishes research in all areas of contemporary soft matter science in which macromolecules play a key role, including nanotechnology, self-assembly, supramolecular chemistry, biomaterials, energy generation and storage, and renewable/sustainable materials. Submissions to ACS Macro Letters should justify clearly the rapid disclosure of the key elements of the study. The scope of the journal includes high-impact research of broad interest in all areas of polymer science and engineering, including cross-disciplinary research that interfaces with polymer science. With the launch of ACS Macro Letters, all Communications that were formerly published in Macromolecules and Biomacromolecules will be published as Letters in ACS Macro Letters.
