Chirality-driven self-sorting is envisaged to efficiently control functional properties in supramolecular materials. However, the challenge arises because of a lack of analytical methods to directly monitor the enantioselectivity of the resulting supramolecular assemblies. Presented herein are two fluorescent core-substituted naphthalene-diimide-based donor and acceptor molecules with minimal structural mismatch and they comprise strong self-recognizing chiral motifs to determine the self-sorting process. As a consequence, stereoselective supramolecular polymerization with an unprecedented chirality control over energy transfer has been achieved. This chirality-controlled energy transfer has been further exploited as an efficient probe to visualize microscopically the chirality driven self-sorting.
手性驱动的自分类被设想为有效地控制超分子材料中的功能性质。然而，由于缺乏直接监测所得超分子组装体对映选择性的分析方法，这一挑战出现了。本文介绍了两种基于荧光核取代萘二酰亚胺的给体和受体分子，它们具有最小的结构不匹配，并且包含强大的自识别手性模体来确定自分类过程。因此，实现了具有前所未有的手性控制的能量转移的立体选择性超分子聚合。这种手性控制的能量转移进一步被用作一种有效的探针，以微观可视化手性驱动的自分类。
