摘要
Chloroprene is a monomer widely used in the production of neoprene,and 1-hydroxy-2-butanone(1H2B)is one of the metabolites of chloroprene in urine,which can place a significant impact on human health by disrupting the normal structure and function of DNA.Herein,a three-dimensional Zn-based coordination polymer(1)and a two-dimensional Cd-based coordination polymer(2)were synthesized with mixed ligands of 2,5-furandicarboxylic acid(H_(2)FDA)and 1,2,4-triazole(Htrz)and fully characterized.2 exhibits excellent stability and superior sensing performance for 1H2B with fast response within 15 s,good recyclability and a detection limit of 9.24μM.In addition,2 demonstrates good selectivity in presence of main coexisting compounds in urine.In-depth in-vestigations of the sensing mechanism revealed that the luminescence sensing is based on the competitive ab-sorption and photoelectron transfer processes.
