Recognition of atomic-level difference in porphyrin dyads for self-sorted supramolecular polymer growth

Year: 2023

Type: article

Abstract: Molecular recognition is a fundamental and significant, naturally occurring phenomenon. Inspired by molecular recognition in biosystems, fine control of supramolecular assemblies through self-sorting behavior in mixed components has become an emerging topic in supramolecular chemistry. The topological control of molecular recognition sites has been extensively investigated to achieve self-sorted supramolecular assemblies. However, despite recent advancements, the design to obtain self-sorted supramolecular assemblies requires a relatively significant structural alteration for topological selection. Therefore, the effect of slight structural changes on the molecular recognition process in supramolecular chemistry remains questionable. In this paper, we report a series of porphyrin dyads (PDMs) with atomic-level differences, showing significant morphological changes in self-assembled structures. Moreover, we observed self-sorting in a mixture of PDMs with atomic-level differences.
