Embodiment

[0046] The following are examples of the present invention, which are helpful for understanding the present invention, but the protection scope of the present invention is not limited to this content.

[0047] (1) Superhydrophobic porous organic polymer containing alkyl chains LNU-29

[0048] 1. The synthetic route is as follows:

[0049]

[0050] 2. The preparation method is as follows:

[0051] 527mg (1.50mmol) of 2,7-dibromo-9,9-dimethylfluorene and 150mg (0.99mmol) of 1,3,5-triethynylbenzene were placed in the reaction vessel, and then 10mg of cuprous iodide and 40mg of tetrakis(triphenylphosphine)palladium were quickly added to the reaction system. The nitrogen degassing process was carried out three times. Under the protection of nitrogen, 20mL N,N'-dimethylformamide and 8mL triethylamine were added to the reaction system, and then the temperature was raised to 80°C and the reaction was stirred for 72h. After the reaction was completed, cool to room temperature and...

Abstract

The invention discloses a super-hydrophobic porous organic polymer containing alkyl chains and a preparation method and application of the super-hydrophobic porous organic polymer containing the alkylchains. 1,3,5-triethynylbenzene and organic compounds containing the different alkyl chains serve as a construction unit, copper iodide and tetrakis(triphenylphosphine)palladium serve as catalysts, reaction is conducted for 72 h at 80 DEG C through a Sonogashira-Hagihara coupling reaction, and thus the super-hydrophobic porous organic polymer LNUs containing the alkyl chains is obtained. According to the preparation method, raw materials are easy to obtain, operation is easy, the environmentally friendly and efficient effects are achieved, and the reaction conditions are mild. The prepared super-hydrophobic porous organic polymer containing the alkyl chains is good in thermal stability and excellent in hydrophobic property. Prepared super-hydrophobic polyester fabric has the stable hydrophobic ability in various environments, and has great application prospects in the sewage treatment fields such as oil-water separation, and adsorption of leaked crude oil or organic solvents.

Description

technical field [0001] The invention belongs to the technical field of new chemical materials, and in particular relates to a preparation method and application of a superhydrophobic alkyl chain-containing porous organic polymer. Background technique [0002] With the rapid development of social economy, industrialization and modernization have brought comfort and convenience to human beings in all aspects, but at the same time, they have also had other adverse effects on the environment, oceans and ecosystems. Petroleum products are widely used in various ways in many fields such as fuel, chemical industry, steel, machinery manufacturing and other industries. While meeting these needs, the discharge of industrial wastewater, petroleum and organic solvents continues to increase, which not only brings huge economic losses , and the environment and ecology have been seriously polluted, even endangering the safety of humans and wild animals. In the past decades, many researche...
