Problems solved by technology

Therefore, it can be used as a material for enriching some important objects, but this kind of macrocyclic fan material has better solubility in solvents, so the separation of host and guest after enrichment needs to consume more solvents and other additives. Therefore, a lot of energy and cost are required, and the process will be relatively complicated; and it will cause a certain amount of loss of the main body after use.
Polyethylene glycol is also a supramolecular host with excellent binding ability, but it is also characterized by good solubility, so after exerting its binding effect, it is usually not recyclable

Abstract

The invention discloses a meshy gel material with a three-ring veratrum hydrocarbon derivate as a node and a preparation method thereof. A three-ring veratrum hydrocarbon derivate molecule with a plurality of phenolichydroxyl serves as the node of a network, polyethylene glycol with different molecular weights serves as network lines, and the three-dimensional meshy gel material is prepared by a synthesis method. A rigid three-ring veratrum hydrocarbon derivate structure in a gel material structure can keep the rigidity due to the characteristics of the derivate structure after being dissolved, so the original combination characteristic between a subject and an object can be kept; and a flexible polyethylene glycol part greatly increases the depth of a cavity of a three-ring veratrum hydrocarbon derivate part, and can adapt to the object by changing the shape of the flexible polyethylene glycol part and the affinity of the overall network to various solvents is enhanced, so the gel material is endowed with the capability of gathering special object molecules.

Description

technical field [0001] The invention relates to a network gel material and a preparation method thereof, in particular to a network gel material with cyclotriveratrol derivatives as network nodes and a preparation method thereof. Background technique [0002] Cyclotriveratrol is a kind of macrocyclic supramolecular host with relatively rigid molecular structure, and the research on it is increasing day by day. Its applications include liquid crystal materials, combination and identification of molecules, ions, etc. For example, fullerenes, carboranes, alkali metal ions, etc. can be combined. However, the molecular weight of cyclotriveratrol is small and due to its structural limitation, it has more requirements on the shape and properties of the guest, so there are fewer types of guests that can be combined. When the polyether chain is introduced into the macrocycle of triveratrol to form a dendritic polymer structure, the cavity of the supramolecular main body becomes dee...
