A multifunctional Zn(II)-based four-fold interpenetrated metal-organic framework for highly sensitive sensing 2,4,6-trinitrophenol (TNP), nitrofurazone (NFZ) and nitrofurantoin (NFT)

摘要

A four-fold interpenetrated Zn(II)-based metal-organic framework of 1, {[Zn(TTPBA-4)(0.5)(TPA)]center dot H2O center dot 0.5DMF}(n), with the mog topology was solvothermally synthesized with mixed ligands of TTPBA-4 (N-1,N-1,N-4,N-4-tetrakis(4-(4H-1,2,4-triazol-4-yl)phenyl)benzene-1,4-diamine) and TPA (terephthalic). 1 shows an intense emission at 443 nm when dispersed in DMAc solvent, which can serve as a multifunctional luminescent sensor to sensitively detect TNP (2,4,6-trinitrophenol), NFZ (nitrofurazone) and NFT (nitrofurantoin).
