    Homo-Chiral and Hetero-Chiral Interaction Regulate on Supramolecular Polymers

    • 摘要: 手性是自然界的基本属性,手性分子是生命体的重要构造基元之一,对维系生命体的结构和功能具有独特作用,因此理解手性特别是超分子手性在超分子结构和功能上的作用具有重要意义。近年来,手性超分子聚合物引起了广泛的关注,有助于理解DNA、蛋白质等生物功能分子的多级次手性结构组装行为。本文从手性构造基元自组装形成手性螺旋结构出发,介绍了对映体混合物中手性相互作用(同手性作用、异手性作用)对超分子聚合物的结构、生长的调控作用,及手性基元之间的选择性对超分子聚合物的生长和功能的影响,为理解超分子体系中的手性相互作用提供了基础。

       

      Abstract: Chirality is the basic feature of nature. Chiral molecules are one of the important structural elements of life and play a unique role in maintaining many biological structures and functions. Therefore, it is of great significance to understand the role of chirality, especially supramolecular chirality, in the view of mimicking chiral structures, such as DNA and proteins, in biological system. Chiral supramolecular polymers, which are formed by components via various noncovalent interactions and the components in those assemblies exhibit the non-symmetric spatial arrangement, are good models to gain sight on the formation and functions of chiral biostructures. The formation of chiral supramolecular polymers is strongly related to both the chirality of the molecular components and their assembly routes. Therefore, it is possible that all kinds of molecules, either chiral or achiral (including racemic mixture), can assemble into chiral nano/microstructures through non-covalent bonds. In this mini-review, we mainly focus on the self-assemblies in the racemic mixture of two enantiomers. The chiral interactions, such as homo-chiral interaction and hetero-chiral interaction, play a subtle role during the formation of supramolecular polymers. The self-sorting assembly originated from homo-chiral interaction (ESS or ERR (interaction between the same enantiomers) >ESR (interaction between the different enantiomers)) and self-reorganized assembly originated from hetero-chiral interaction (ESS or ERRESR) are reviewed. The chiral sense of formed nanostructures and length of supramolecular polymers can be tuned by controlling the homo-chiral or hetero-chiral interactions. Further, the stereoselective energy transfer has been introduced as an example of chirality-driven function of supramolecular polymers.
