Embodiment Construction

[0031] The preparation of the supramolecular organic framework NBP5-TG of the present invention and its application to the adsorption of organic dyes in aqueous solution will be further described below through specific examples.

[0032] Synthesis of Supramolecular Organic Framework NBP5-TG

[0033] 1. Synthesis of host NBP5

[0034] (1) Synthesis of compound 1: Add 400mL acetone to a 500mL round bottom flask, add 4-methoxyphenol (2.48g, 20mmol), 1,4-dibromobutane (17.20mL, 80mmol), add K 2 CO 3 (8.40g, 60mmol) and KI (3.30g, 20mmol), add one or two drops of polyethylene glycol as a phase transfer catalyst, reflux at 60°C for 2 days, remove the solvent after the reaction, and separate by column chromatography to obtain compound 1 As a white solid (4.96g), the yield was 95%;

[0035](2) Synthesis of compound 2: Add 80mL of 1,2-dichloroethane into a 100mL round-bottomed flask, add 1 (1.29g, 5.0mmol), 1,4-dimethoxybenzene (2.76g, 20.0 mmol) and paraformaldehyde (0.75g), add 3...

Abstract

The invention designs and synthesizes a supramolecular organic framework NBP5-TG based on dipillar[5]arene. The NBP5-TG is formed by assembling and complexing p-hydroxybenzaldehyde functionalized dipillar[5]arene (NBP5) serving as a subject and a 4-aminopyridine functionalized tripodal compound (TG) serving as an object in a DMSO / H2O binary system. The supramolecular organic framework NBP5-TG canreact with various organic types of dye in water, so that efficient adsorption of the organic dye is realized. Experiments show that the removal rate of the supramolecular organic framework NBP5-TG onorganic dye in an aqueous solution can reach 80% or above, so that the supramolecular organic framework NBP5-TG can be applied to adsorption of organic dye in wastewater.

Description

technical field [0001] The present invention relates to a supramolecular organic framework, in particular to a supramolecular organic framework based on bicolumn [5] arene; the present invention also relates to the application of the supramolecular organic framework in efficient adsorption of organic dyes in aqueous solution, which belongs to chemical synthesis field, the adsorption field of organic dyes. Background technique [0002] With the industrialization of the world, the discharge of a large amount of dye wastewater produced by the textile, leather, paper and printing industries has caused serious environmental problems. These pollutants accumulate in the water to a certain extent, which will exceed the self-repair ability of the environment, thus causing harm to human beings. Causes irreversible damage to the health of other creatures. There are many methods for detecting and removing pollutants of these organic dyes, such as chemical methods such as oxidation, pho...
