Metal ‘turn-off’, anion ‘turn-on’ gelation cascade in pyridinylmethyl ureas

Offiler, Caroline A.; Jones, Christopher D.; Steed, Jonathan W.

Abstract

Pyridinylmethyl ureas form strong gels in aromatic solvents. The gels are weakened or destroyed by addition of transition metal ions but gelation is recovered by adding bromide anions giving rise to a gel–sol–gel chemically triggered cascade.
