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

    • 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.
