Supramolecular gels,a novel "soft material",have drawn increasing attentions due to their widely applications in sensing,catalysis,drug delivery,and tissue engineering. As the low molecular mass organic gelators(LMOGs)self-assembled into 3D network in water,hydrogel has become a hotspot in supramolecular gels ascribing to its better biocompatibility. Crucially,bearing the non-covalent bonds’ characters,supramolecular hydrogel usually display satisfactory phase translation towards external stimuli including pH,temperature,pressure,and so ***,the chemical reagent enhanced hydrogel has rarely been ***,the enantiomers of urea derived alanine were designed and synthesized as gelators,which was fully *** solution of the gelators and 2 *** gradually turned to stable hydrogel with the addition of glucosactone,which could release proton in *** morphological investigation indicated that the gelators form fibers firstly,which was further connected to form 3D *** interestingly,the enantiomers lead to various chiral fibers,that is,L-alanine derivatives creates left-handle helical fiber and the D-alanine derivatives is right-handle *** results will provide a novel avenue to construct chiral hydrogel.
