A highly selective, Hg~(2+) triggered hydrogelation: modulation of morphology by chemical stimuli

摘要

We report the first Hg~(2+) selective hydrogelation by 4'-[4-(4-amino-phenyl)phenyl]-2,2':6',2"-terpyridine. The gel showed remarkable response towards specific chemical agents such as benzo-18-crown-6 ether and K~+ which enabled extensive modulation of the gel morphology.
