Developing a novel pyridine-based ionic porous organic polymer with functional group for highly efficient extraction of phenolic endocrine disruptors in natural water and tilapia fish.

A pyridine-based ionic porous organic polymer bearing hydroxyl groups (OH-iPOP) was developed for the first time by quaternization and crosslinking of 4-pyridinemethanol with 4,4'-bis(chloromethyl)biphenyl. OH-iPOP exhibited strong adsorption capacity for endocrine disruptors (EDs) including bisphenol A, bisphenol F, p-tert-butylphenol and bisphenol B (82.59-183.
