Embodiment Construction

[0023] The preparation and application of the supramolecular polymer reticular gel of the present invention will be further described through specific examples below.

[0024] 1. Synthesis of DP5 of the main compound

[0025] (1) Synthesis of mercaptoacetazide pillar[5]arene SP5J with four carbons on one side: see literature J. Liu, Y. Q. Fan, S. S. Song, G. F. Gong, J. Wang, X. W. Guan, H. Yao, Y. M. Zhang, T. B. Wei, and Q. Lin. ACS Sustainable Chem. Eng., 2019, 7(14): 11999-12007. The structural formula of SP5J is as follows:

[0026]

[0027] (2) Synthesis of DP5: add 0.4934g (0.55mmol) SP5J, 3 drops of glacial acetic acid and 0.0336g (0.25mmol) terephthalaldehyde in 30mL of absolute ethanol, stir and reflux at 80~85℃ for 12 hours and then statically Place and cool to room temperature. At this time, a large amount of light yellow solid precipitated. After suction filtration and rinsing with cold absolute ethanol, 0.3850 g of light yellow powdery solid was obtained wit...

Abstract

The present invention designs and synthesizes a supramolecular polymer network gel complexed with host and guest, which uses mercaptoacetylhydrazone functionalized bicolumn[5]arene as the main compound, and 4-aminopyridine-modified tripod compound as the guest compound , heated and dissolved in DMSO / H 2 In the mixed solvent of O, the supramolecular polymer gel is synthesized through host-guest interaction complexation; the supramolecular polymer gel is freeze-dried to obtain xerogel. The dry gel has a good adsorption and removal effect on organic dyes, especially for crystal violet and rhodamine B, with a high removal rate: the removal rate of crystal violet is 96.3%, and the removal rate of rhodamine B is 95.4%. , so it can be used to remove organic dyes in aqueous solution.

Description

technical field [0001] The present invention relates to a supramolecular polymer network gel complexed with host and guest, in particular to a kind of functionalized bicolumn [5] arene with mercaptoacetylhydrazone as the main compound, and a tripod compound modified with 4-aminopyridine as the guest The compound, a supramolecular polymer network gel complexed by host-guest interaction, is mainly used for the removal of organic dyes, and belongs to the field of supramolecular materials and the field of organic pollutant removal. Background technique [0002] Supramolecular polymer is the intersection of supramolecular chemistry and polymer chemistry. Compared with traditional polymers, supramolecular polymers are formed by the combination of monomers through non-covalent weak interactions. Owing to the dynamic and reversible nature of noncovalent interactions, supramolecular polymers display many unique properties, such as response to external stimuli, reversible shear sensi...
