Abstract

Roxarsone(ROX)is a commonly used antibacterial and growth-promoting additive to animal feed.The development of an effective method for detecting ROX and its conversion products is of importance be-cause of their potential harm to human health and ecosystem.Herein,we report the designed synthesis of a novel one-dimensional covalent organic framework(1D COF),named EP-COF,and its application as a fluorescent probe for ROX sensing.EP-COF is constructed based on imine linkages,exhibiting high crys-tallinity,strong fluorescence emission,and good dispersibility in water.It displays a remarkable capability to efficiently detect ROX,with an impressive detection limit of 4.5nmol/L.Moreover,EP-COF also offers advantages of excellent selectivity,and high structural stability.This work not only presents a promising approach for the detection of harmful substances like ROX,but also serves as a valuable reference for exploring application of 1D COFs in chemical sensing.
