The invention discloses a three-legged quasi-rotaxane supramolecular organogel based on trimesoyl chloride, which is trimesoyl chloride functionalized with pillar[5] arene and 4-aminopyridine, and fully dissolved in DMSO under heating ‑H 2 O to obtain a transparent solution; cooled to room temperature to form a stable supramolecular organogel TP‑Q with blue-white aggregated fluorescence. Adding a series of cation solutions to TP-Q, only the addition of Fe 3+ can quench its fluorescence, so TP-Q can specifically and selectively recognize Fe 3+ . Three-legged pseudorotaxane supramolecular organogel and ferric perchlorate hexahydrate were heated and dissolved in DMSO-H 2 O, and after cooling, a metal-organogel was formed. When a series of anions were added to the metal-gel, only The addition of F- can turn on the fluorescence of the metal gel, and the fluorescence changes from black to blue-white, thus realizing the high - sensitivity detection of F-. |
