摘要

A novel supramolecular gelator (C11) based on a carboxylic acid-functionalized benzimidazole was synthesized, which could form an organogel (C11-OG) and generate a metallogel (Pb-MG) with Pb2+. Both of the supramolecular gels exhibit aggregation-induced enhanced emission (AIEE). The Pb-MG shows outstanding reversible sol-gel transitions induced by the change in temperature, EDTA and Na2S. It has the potential to be widely applied in materials science.
