[0063] Example 4 Detection of lipophilic superhydrophobic porous aromatic framework material

[0064] Figure 1-1 to Figure 1-3 , is the lipophilic superhydrophobic porous aromatic skeleton material LNU-25 (a) prepared by embodiment 1, embodiment 2, embodiment 3, LNU-26 (b) and LNU-27 (c) and corresponding monomer thereof Infrared spectra. It can be seen from the figure that the characteristic absorption of the reaction monomer 2,7-dibromo-9-fluorenone, 2,7-dibromo-9,10-phenanthrenequinone and 2,6-dibromoanthraquinone C-Br bond Peak (495cm -1 ) disappears in the product to prove the cleavage of the C-Br bond in the monomer; the C-H bond at the end of the monomer alkynyl group (3300cm -1 ) disappears in the polymer; near 2200cm in the infrared spectrum of the final product -1 The characteristic absorption peak of the alkynyl group -C≡C- can be seen, and the above results prove the success of the polymerization reaction.

Abstract

The invention belongs to the technical field of chemistry and new materials, and particularly relates to an oleophylic super-hydrophobic porous aromatic framework material as well as a preparation method and application thereof. The oleophylic super-hydrophobic porous aromatic framework material LNUs is synthesized by carrying out Sonogashira coupling reaction on 1, 3, 5-triacetylene benzene as aconstruction element and different brominated benzene ring-containing compounds, and the contact angles of the materials of the kind are all greater than 150 degrees. The materials can be successfullyloaded on polyester fabric in a simple soaking mode, and the prepared oleophylic super-hydrophobic polyester fabric can be used for effective separation of an oil/water mixture or an organic solvent/water mixture. The synthesis method of the oleophylic super-hydrophobic porous aromatic framework material provided by the invention is simple in process and remarkable in hydrophobic effect. The prepared oleophylic super-hydrophobic polyester fabric can keep excellent hydrophobic performance under severe conditions such as strong acid, strong alkali or high temperature, and has a good applicationprospect in the field of oil/water separation.

Description

technical field [0001] The invention belongs to the technical field of chemistry and new materials, and in particular relates to a preparation method of an lipophilic superhydrophobic porous aromatic framework material. Background technique [0002] With the development of industrialization, the leakage of industrial chemicals and oil has caused serious damage to the environment, especially the aquatic ecosystem. Therefore, how to efficiently separate oil or organic solvents from water has become an urgent problem for scientists to solve. Currently commonly used separation technologies such as in-situ combustion, absorption, membrane filtration and chemical treatment have been widely used to clean up oily or industrial wastewater. Among them, the absorption method is the most economical and eco-friendly, because the adsorption produces no secondary pollution and has a good separation effect on the oil / water mixture. At present, people have discovered and synthesized many ma...
