<i>In situ</i> aldehyde-modification of self-assembled acyl hydrazide hydrogels and dynamic component selection from complex aldehyde mixtures

Abstract

Self-assembled hydrogels based on the industrially-relevant 1,3:2,4-dibenzylidene sorbitol framework functionalised with reactive acyl hydrazide (DBS-CONHNH2) peripheral groups react with aldehydes without disrupting the nanoscale gel network, adapting gel performance, and dynamically selecting specific aldehyde components from complex mixtures.
