摘要：
A novel Pb2+-specific metallohydrogel HAIP-Pb was synthesized. HAIP-Pb possesses multi-stimuli responsiveness, including to pH, temperature, etc. Various measurements were performed to gain insights into themechanism of gelation. The HAIP gelator can gel Pb2+ and simultaneously adsorb toxic dyes. Intriguingly, HAIP can cause gelation of soil containing Pb2+ ions.
