Abstract
Molecular recognition of simple sugars is crucial due to their essential roles in most living organisms. However, it remains extremely challenging to achieve a visual recognition of simple sugars like sucrose in water media under physiological conditions. In this article, the visual recognition of sucrose is accomplished by a chiral supramolecular hydrogel formation through the co-assembly of a two-component fibrous solution (l-phenylalanine based gelator co-diaminopyridine, LDAP) and sucrose. H-bonding between the amino group of LDAP and the hydroxyl group of sucrose facilitates the gelation by loading sucrose into the LDAP solution. The formed hydrogel showed an amplified inversion of circular dichroism (CD) signals as compared to the corresponding LDAP solution. In addition, the effective chirality transfer was accompanied by a bathochromic shift in UV–Vis and FL spectra of the gel. Such a simple and straightforward chiral co-assembled strategy to visually recognize sucrose will have the potential use of smart gelators in saccharides separation and proteomics to be further applied in medical diagnostics and cell imaging.Graphic Abstract
