4-Hydroxybenzaldehyde derived Schiff base gelators: case of the sustainability or rupturing of imine bonds towards the selective sensing of Ag+ and Hg2+ ions via sol–gel methodology

Cholesterol appended 4-hydroxybenzaldehyde derived Schiff bases 1–4 were designed and synthesized. They are explored for the naked-eye detection of metal ions using sol–gel methodology that involved the imine bonds remaining intact or rupturing. All the compounds form a gel under different condition...
