Since the first polymers were discovered, scientists have debated their structures. Before Hermann Staudinger published the brilliant concept of macromolecules, polymer properties were generally believed to be based on the colloidal aggregation of small particles or molecules. From 1920 onwards, polymers and macromolecules are synonymous with each other; i. e. materials made by many covalent bonds connecting monomers in 2 or 3 dimensions. Although supramolecular interactions between macromolecular chains are evidently important, e. g. in nylons, it was unheard of to proposing polymeric materials based on the interaction of small molecules. Breakthroughs in supramolecular chemistry, however, showed that polymer materials can be made by small molecules using strong directional secondary interactions; the field of supramolecular polymers emerged. In a way, we have come full circle. In this essay we give a personal story about the birth of supramolecular polymers, with special emphasis on their structures, way of formation, and the dynamic nature of their bonding. The adaptivity of supramolecular polymers has become a major asset for novel applications, e. g. in the direction for the sustainable use of polymers, but also in biomedicine and electronics as well as self‐healing materials. The lessons learned in the past years include aspects that forecast a bright future for the use of supramolecular interactions in polymer materials in general and for supramolecular polymers in particular. In order to give full tribute to Staudinger in the year celebrating 100 years of macromolecules, we will show that many of the concepts of macromolecular polymers apply to supramolecular polymers, with only one important difference with fascinating consequences: the dynamic nature of the bonds that form polymer chains.

超分子聚合物–我们已经全面发展

自从发现第一批聚合物以来,科学家们一直在争论其结构。在赫尔曼·施陶丁格(Hermann Staudinger)发表大分子的杰出概念之前,通常认为聚合物的特性是基于小颗粒或分子的胶体聚集。从1920年开始,聚合物和大分子彼此成为同义词。一世。e。由许多以2或3维连接单体的共价键制成的材料。尽管大分子链之间的超分子相互作用显然是重要的,例如。G。在尼龙中,基于小分子的相互作用提出聚合材料是闻所未闻的。然而,超分子化学方面的突破表明,高分子材料可以由小分子通过强方向性的二次相互作用而制得。超分子聚合物领域出现了。在某种程度上,我们已经走了一大圈。在本文中,我们将讲述超分子聚合物的诞生,并特别强调其结构,形成方式以及其键合的动态性质。超分子聚合物的适应性已经成为新型应用的主要资产,例如,聚合物。G。不仅可以用于聚合物的可持续利用,还可以用于生物医学,电子和自愈材料。过去几年中吸取的教训包括预测超分子相互作用在聚合物材料中尤其是在超分子聚合物中的应用前景广阔的方面。为了向纪念施陶丁格(Staudinger)庆祝大分子100年的年份表示敬意,我们将展示许多大分子聚合物的概念适用于超分子聚合物,
