Embodiment Construction

[0039] The preparation of gel factor of the present invention, organometallic gel and identification in fluorescence colorimetry below by embodiment - The application is further explained.

[0040] 1. Synthesis of gelling factor L1-p-nitrobenzene-methylene-3,4,5-tris(hexadecyloxy)benzoylhydrazone

[0041] (1) Synthesis of 3,4,5-tris(hexadecyloxy)methyl benzoate: 0.92g (5.0mmol) methyl gallate, 4.2g (30.0mmol) anhydrous K 2 CO 3 , 1.20g (7.0mmol) KI and 30 mL of acetone were mixed, heated to 60°C, and refluxed for 2h, then 5.49g (18.0mmol) of 1-bromo-n-hexadecane was slowly added dropwise thereto, and then refluxed for 72h. After the reaction was complete, evaporate the acetone to dryness, add CHCl 3 Extract 3 times, filter, wash the filtrate once with distilled water, then wash 2 times with 2% NaOH solution, then wash 3 times with saturated NaCl solution, and finally wash with anhydrous NaOH solution 2 SO 4 Dry, rotary evaporate to remove CHCl 3 , the product 3,4,5-tris(...

Abstract

The invention provides a long-chain p-nitrobenzoylhydrazone gelator. One side of the gelator is three long alkyl chains which have 16 C and are obtained through etherification, and the three long alkyl chains can form initial driving force for gelation through mutual action among carbon hydrogen; middle -NH obtained through a hydrazinolysis reaction can form stable gel with -CH and C=O adjacent to -NH through action of intermolecular hydrogen bonds and can also form corresponding binding sites with metal ions through coordination so as to further form the organic metal gel; the formed organic metal gel can realize rapid highly-selective fluorescent recognition of I<-> in water and is obvious in color changes, which enables detection with the naked eyes to be conveniently and rapidly realized; and the formed organic metal gel has good stability, is easy to store and carry and convenient to use and can be used for writing and storage of confidential materials.

Description

technical field [0001] The present invention relates to a p-nitrobenzoylhydrazone gelling factor; the present invention also relates to an organometallic gel based on the gelling factor; the present invention also relates to the application of the organometallic gel in fluorescence recognition of iodide ions, The invention belongs to the technical field of organic synthesis and the technical field of anion detection. Background technique [0002] Iodine is an essential trace element for the human body. It has an important impact on human brain function, cell development, nerve activity, metabolism and thyroid function. Iodine deficiency or excess iodine intake can lead to diseases such as goiter, hypothyroidism and hyperthyroidism. I - It has a wide range of applications in chemical fields such as drug synthesis. Therefore, I - Analysis and detection is a very important task. Commonly used I - The detection methods include gas chromatography-mass spectrometry, capillar...
