摘      要：Molecular recognition of simple sugars is crucial due to their essential roles in most living ***,it remains extremely challenging to achieve a visual recognition of simple sugars like sucrose in water media under physiological *** 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 *** formed hydrogel showed an amplified inversion of circular dichroism(CD)signals as compared to the corresponding LDAP *** addition,the effective chirality transfer was accompanied by a bathochromic shift in UV-Vis and FL spectra of the *** 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.
