Preparation and application of tetra (4-ethynylphenyl) methane porous organic polymer

The invention discloses a tetra (4-ethynylphenyl) methane porous organic polymer which is obtained by connecting azo calixarene through tetra (4-ethynylphenyl) methane. The polymer material has the characteristics of large specific surface area and multiple specific recognition functional groups (azo groups), shows good extraction performance on endocrine disruptors in food and environment, can be used for a sample pretreatment technology of the endocrine disruptors in the food or environment, can enrich target analytes while reducing matrix interference of the target analytes, and can be used for detecting the endocrine disruptors in the food or environment. The accurate analysis and detection of the endocrine disrupter in food and environment are realized. In addition, the material has good chemical stability and can be repeatedly used. 本发明公开了一种四(4-乙炔基苯基)甲烷类多孔有机聚合物，由偶氮杯芳烃通过四(4-乙炔基苯基)甲烷连接而得。该聚合物材料具有比表面积大，特异性识别官能团（偶氮基）多的特点，对食品和环境中内分泌干扰物质表现出良好的萃取性能，可用于食品或环境中内分泌干扰物的样品前处理技术，降低目标分析物的基质干扰的同时对其进行富集，实现食品和环境中内分泌干扰物的精
