Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Three multi‐responsiveness supramolecular metal‐organic gels (MOGs) have been prepared upon Ba(OAc)₂, CdSO₄·8H₂O and Pb(NO₃)₂ with a simple ligand (G17) based on a carboxyl‐functionalized benzimidazole derivative in alcoholic‐water solutions. The MOGs display the formation of well‐developed nanofibrillar networks composed of intertwined fibers which provide stability to gels structures through coordination, hydrogen bonding and π‐ π interactions characterized by using field emission scanning electron microscopy (FESEM), the fourier transform infrared (FT‐IR) spectroscopy and powder X‐ray diffraction (XRD) techniques. MOG‐1 shows good stimuli responsiveness toward the changes in K₂CrO₄, both MOG‐2 and MOG‐3 do good job toward the changes in Na₂S. Moreover, because these MOGs were formed easily by gelator with some heavy metal ion, such as Cd(II) and Pb(II), it might provide the basis for heavy metal ion capture and removal.</p> </abstract>
