Embodiment 1

[0045] (1) Synthesis of products

[0046] 1. Synthesis: Put 2mmol of 1,4-diethynylbenzene, 2mmol of 2,4,6-tribromophenol, 100mg of tetrakis(triphenylphosphine)palladium, and 30mg of cuprous iodide in 100ml to dry in a round bottom flask. Pass argon gas into the round bottom flask and exhaust the air for 20 minutes to form an anhydrous and oxygen-free environment. Then add 3ml of toluene and 3ml of triethylamine into the device with a syringe, stir vigorously under argon atmosphere, then raise the temperature to 80°C, and react for 10h.

[0047] 2. Filtration: Wash the product with dichloromethane, acetone, deionized water, and methanol, and vacuum-dry it at 120°C for 3 hours to obtain an organic conjugated polymer.

[0048] Following formula is the synthetic main reaction formula of organic conjugated polymer of the present invention:

Abstract

The invention discloses an elastic hydrophobic organic conjugated polymer, a synthesizing method thereof and an application thereof to removing of organic matters from water. The synthesizing method comprises the following steps of: connecting a benzene ring with an acetylene bond; particularly adding a catalyst, a nonpolar solvent and the like into 1.4-diacetylene-benzene and a 1,3,5-tribromobenzene derivative or a 1,3,5-triiodo benzene derivative serving as substrates in an inert atmosphere; undergoing a polymerization reaction; and filtering, washing, drying and the like to obtain a product. The product is centimeter grade or millimeter grade elastic particles containing a plenty of mesopores and gaps, so that material density is very low; and meanwhile, the copolymer has high elasticity and high hydrophobic property. When adsorption of liquid organic matters is saturated in the polymer, the polymer is taken out of an aqueous solution, organic matters are removed through mechanicalextrusion, and polymer particles can be used repeatedly, so that the cost on removal of the organic matters from water is lowered. The elastic hydrophobic organic conjugated polymer is suitable for batch production and environmental protection.

Description

technical field [0001] The invention belongs to the field of polymer material synthesis and application, in particular to a method for synthesizing an elastic hydrophobic organic conjugated polymer and the application of the organic conjugated polymer in removing organic matter in water. Background technique [0002] The increasingly scarce fossil resources and the deteriorating ecological environment are global problems, which make the research on clean energy and environmental protection more and more important. Porous materials with large specific surface area and good pore properties have attracted the attention of many scientists and are widely used in gas storage, adsorption separation, catalytic chemistry and other fields. [0003] Organic conjugated polymer is a new type of porous material. This porous material is mainly composed of light elements such as carbon, hydrogen, and oxygen, connected by organic covalent bonds. Since the polymer contains both mesopores and ...
