Pillararenes, a new kind of macrocyclic aromatic compounds, are closely attracted because it was used to construct supramolecular gels. In this paper, an iodine-functionalized pillar[5]arene was designed and synthesized. This pillar[5]arene can form a stable supramolecular organogel in cyclohexanol, and phase transition temperature is approximately 96 ℃. The formation process of the organogel was characterized by concentration dependent 1H NMR spectrum, 2D NOESY experiment, X-ray diffraction (XRD) powder diffraction and scanning electron microscope. The experiment results showed that a sheet-like structure was formed in self-assembly process of iodine-functionalized pillar[5]arene. Meanwhile, the fluorescent recognition properties of organogel were studied. With the addition of 0.5 equiv. of various metal ions (Fe3+, Ag+, Ca2+, Co2+, Ni2+, Cd2+, Pb2+, Zn2+, Cu2+, Mg2+ and Hg2+) onto the organogel, Hg2+ and Ag+ can cause blue fluorescence quenching of the organogel after 10 min. Therefore, this gel can be used for fluorescent detection of Hg2+ and Ag+.
