Abstract

The invention provides a COF-5 one-dimensional rod-like crystal material and a preparation method thereof. The preparation method comprises the following steps: step 1, mixing 2, 3, 6, 7, 10, 11-hexahydroxy triphenyl, 1, 4-phenyldiboronic acid, 1, 3, 5-trimethylbenzene and 1, 4-dioxane in an addition ratio of (0.1-0.3) mmol: (0.1-0.5) mmol: (10-15) mL: (10-15) mL in an anhydrous and anaerobic environment to form a mixture; 2, sealing the mixture, carrying out ultrasonic dispersion, and oscillating to obtain a uniform dispersion liquid; 3, heating the dispersion liquid to a certain temperature,and reacting for a period of time; and step 4, washing an obtained reaction product, then carrying out vacuum drying, finally introducing a protective gas, and carrying out heat treatment for a period of time at a set temperature to obtain the COF-5 one-dimensional rod-like crystal material. The method is simple in preparation process, and the prepared product is good in growth and regular in morphology.

Description

technical field [0001] The invention belongs to the technical field of porous materials, and in particular relates to a COF-5 one-dimensional rod-shaped crystal material and a preparation method thereof. Background technique [0002] Covalent organic framework materials were first combined by Omar Yaghi in 2005. They are a new type of organic porous polymers with periodicity and crystallinity. These materials are composed of light elements such as C, H, O, N, and B. Formed by strong covalent bonds, it has the characteristics of low density, high thermal stability, high chemical stability and high specific surface area. Due to its strong gas adsorption capacity, COF materials were originally used to store hydrogen, carbon dioxide, sulfur dioxide and other gases, and have been widely used in fuel cells, new energy vehicles, industrial waste gas treatment and other related fields, and have been industrialized. With the in-depth study of COF materials, researchers have found th...
