Abstract

The invention provides a preparation method and an application of a COF (covalent organic framework) material. The COF material is formed by repeating units shown in the description; the COF materialhas excellent chemical and thermal stability, large specific surface area and high crystallinity, and higher enrichment factor and lower detection limit are obtained when the COF material is used forenriching and detecting phenol. According to the provided preparation method of the COF material, all that is needed is to conduct a reaction at room temperature, and reaction conditions are mild.

Description

technical field [0001] The present disclosure relates to a preparation method and application of a covalent organic framework material. Background technique [0002] The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Covalent organic frameworks (COFs), two-dimensional and three-dimensional framework crystalline porous materials constructed by atomically precise combinations of various building blocks. As a kind of crystalline porous material, COFs materials are synthesized from various building blocks through different covalent bonding methods, so they have many advantages, such as various topological structures, regular structures, uniform channels, high thermal stability and chemical stability. [0004] Solid-phase microextraction, a sample pretreatment method with great potential, has won widespread attention due to its advantages such as simple and economical steps, sensit...
