Abstract

The invention discloses a porous organic polymer framework material and a preparation method and application thereof, and belongs to the technical field of chemical and new materials. The porous organic polymer framework material connected by using methylene is obtained under the catalysis of a lewis acid catalyst by using 2,7-di(nitrogen-carbazolyl)-9 fluorenone as a structural unit and formaldehyde dimethyl acetal as a cross-linking agent, and the porous organic polymer framework material can be applied to selective imine synthesis from photocatalysis of organic amine or selective sulfoxide synthesis from photocatalysis of thioether. The porous organic polymer framework material has the characteristics of simple operation, mild reaction conditions, wide applicability and the like.

Description

technical field [0001] The invention belongs to the technical field of chemistry and new materials, and in particular relates to a porous organic polymer material and its preparation method and application. Background technique [0002] Compared with traditional fossil energy, light energy is a cheap, clean and pollution-free green energy. It is abundant in nature, and it is very easy to use, so it has high potential application prospects. As people pay more and more attention to the environmental pollution caused by industrial production, the effective use of light energy has become a hot research topic today. [0003] Porous organic polymers are a new class of porous materials with unique properties such as high specific surface area, low skeletal density and excellent chemical stability. They have been used in gas storage, adsorption and separation, heterogeneous catalysis, energy storage, Fields such as organic optoelectronics show potential applications. Compared wit...
