Embodiment 1、 3

[0052] Embodiment 1, the synthesis of tripod pseudorotaxane supramolecular organogel TP-Q

[0053] (1) Synthesis of pillar[5]arene TP: see T. Ogoshi, S. Kanai, S. Fujinami, T.Yamagishi and Y. Nakamoto, J. Am. Chem. Soc., 2008, 130, 5022 for details;

[0054] (2) Synthesis of 4-aminopyridine-functionalized trimesoyl chloride gelling factor Q: see X.Z. Luo, X. J. Jia, J. H. Deng, J. L. Zhong, H. J. Liu, K. J. Wang, and D. C.Zhong, J. Am. Chem. Soc., 2013, 135, 11684-11687;

[0055] (3) Synthesis of tripod pseudorotaxane supramolecular organogel (TP-Q): Weigh 4-aminopyridine-functionalized trimesoyl chloride gel factor Q (4.1mg, 0.0093mmol) and put it on the column[5] Aromatic TP (20.2 mg, 0.027 mmol), added to 0.5 mL DMSO-HO 2 O (0.3 mL DMSO, 0.2 mL H 2 O), fully dissolved under heating to obtain a transparent solution; cooled to room temperature, the transparent solution formed a stable supramolecular organogel TP-Q.

Embodiment 2

[0056] Embodiment 2, TP-Q fluorescent recognition Fe 3+

[0057] Take 13 small amounts (about 0.02g) of organogel TP-Q on a white drip plate, and add 20 μL of different cations (C=0.1moL / L, Mg 2+ , Ca 2+ , Cr 3+ , Fe 3+ ,Co 2+ , Ni 2+ , Cu 2+ , Zn 2+ , Ag + , Cd 2+ , Hg 2+ , Pb 2+ ) in aqueous solution. Observe the fluorescence color change under the ultraviolet light. If the fluorescence color of organogel TP-Q changes from blue-white to black, it means that Fe is added. 3+ Solution, if the fluorescent color of TP-Q does not change, it means that the aqueous solution of other cations is added.

Embodiment 3

[0058] Embodiment 3, supramolecular metal gel TP-Q+Fe 3+ preparation of

[0059] Weigh column [5] arene TP (20.2 mg, 0.027 mmol), 4-aminopyridine functionalized trimesoyl chloride gelling factor Q (4.1 mg, 0.0093 mmol) and ferric perchlorate hexahydrate (4.6 mg, 0.010 mmol), added together to 0.5mL DMSO-H 2 O (0.3 mL DMSO, 0.2 mL H 2 O), heated to dissolve it, and cooled to room temperature to form a supramolecular organogel based on tripod quasirotaxane (TP-Q+Fe 3+ ).

Abstract

The invention discloses tripodia pseudorotaxane supramolecular organic gel based on trimesoyl chloride. According to the tripodia pseudorotaxane supramolecular gel based on the trimesoyl chloride, thepillar[5]arene and 4-aminopyridine functionalized trimesoyl chloride is fully dissolved into DMSO-H2O under the heating condition so as to obtain a transparent solution; cooling is carried out to reach room temperature so as to form the stable supramolecular organic gel TP-Q with blue and white aggregation-state fluorescence; a series of cationic solutions are added into the TP-Q, and fluorescence quenching can be realized only by adding Fe3+>, so that the TP-Q can specifically and selectively recognize the Fe3+>; and the tripodia pseudorotaxane supramolecular organic gel and ferric perchlorate hexahydrate are heated and dissolved in the DMSO-H2O, then cooling is carried out so as to obtain metal organic gel, when a series of anions are added into the metal gel separately, the fluorescence of the metal gel can be opened only by adding F<->, the fluorescence is changed into blue and white from black, and therefore high-sensitivity detection of the F<-> is realized.

Description

technical field [0001] The invention relates to a tripod quasirotaxane supramolecular gel based on trimesoyl chloride and the selective fluorescence recognition of the supramolecular organogel. 3+ application in; the present invention also relates to a metal organic gel based on the tripod quasirotaxane supramolecular gel and the metal gel in the selective fluorescence recognition F - The application of the invention belongs to the technical field of supramolecular organogel and the technical field of ion detection. Background technique [0002] Supramolecular organogels are low-molecular-weight organic compounds (gelling factors) that undergo multiple hydrogen bonds, van der Waals forces, π-π Supramolecular (soft) materials formed by self-assembly of weak interactions between molecules such as stacking and hydrophilic-hydrophobic interactions. This kind of material has the unique advantages of both solid materials and liquid materials: supramolecular organogel molecules m...
