Popis:	A multi-responsiveness supramolecular metal-organic gel (MOG) has been prepared by using silver (I) nitrate and a simple ligand (L17) based on a biscarboxyl-functionalised benzimidazole derivative. The MOG that displays the formation of well-developed nanofibrillar networks composed of intertwined fibres was characterised by using field emission scanning electron microscopy (FESEM), Fourier transform infrared (FT-IR) spectroscopy and powder X-ray diffraction (XRD) techniques. The FT-IR spectra and XRD show that supramolecular MOG was formed through an effective coordination of the ligand and Ag+. This MOG reveals outstanding reversible sol–gel transitions induced by changes of temperature and pH, as well as by addition of NH4OH, ethylene diamine tetraacetic acid and Na2S. In addition, the MOG also shows a good ability in dye sorption. These results demonstrate that this multichannel responsive smart MOG has the potential to be widely applied in materials science.
