Abstract

A hydrogen bond covalent organic polymer material H C The synthetic method of OP-7, this method is: dissolving benzene-1,3,5-trihydrazide in the organic solvent dimethyl sulfoxide, keeping its concentration at 0.04 mol / L, named as A solution. Dissolve 1,3-bis(4-pyridyl)propane in solution A, keep its concentration at 0.06 mol / L, and name it solution B. Dissolve 4,4-biphenyldicarbaldehyde in solution B, keep its concentration at 0.06 mol / L, and name it solution C. The molar ratio in solution C is: benzene-1,3,5-trihydrazide: 1,3-di(4-pyridyl)propane: 4,4-biphenyldicarbaldehyde=2:3:3. Place C solution in a constant temperature oil bath and heat to obtain a yellow polymer. The yellow polymer was placed in a dialysis bag and dialyzed to obtain the obtained product. The resulting obtained material was poured into a beaker, followed by freeze-drying to obtain a hydrogen-bonded covalent organic polymer material H C OP-7.

Description

technical field [0001] The invention belongs to the field of preparation of nanomaterials and environmental materials, and relates to a hydrogen bond covalent organic polymer material H C Synthetic method of OP-7. Background technique [0002] The backbone of covalent organic polymers COPs (Covalent Organic Polymers) is composed of light elements (B, C, N, O, Si), its structure and function can be pre-designed, and it has a high specific surface area and good chemical stability and thermal stability. It has a wide range of applications in the fields of energy, medicine and the environment. Usually, COPs contain only two monomers, a reversible covalent bond, which severely limits the development of COPs. [0003] The present invention utilizes the orthogonal reaction of imine chemistry and hydrogen bond to design a novel three-component hybrid hydrogen bond covalent organic polymer material H C OP-7. Design ideas: ①The ternary system composed of three monomers is more in...
