A multifunctional 3D Cd-based metal-organic frameworks for the highly luminescence sensitive detection of CrO42−/Cr2O72− and nitro aromatic compounds

Abstract A novel 3D Cd(II)-based luminescent metal-organic framework {[Cd(L)(bpe)0.5]·H2O}n (1) [L = 6-(3-pyridyl)isophthalic acid and 1,2-bis(4-pyridyl)ethane], has been successfully assembled by a solvothermal reaction. The structure displays 4,5-connnected framework and exhibits solvent stability. More importantly, the excellent sensitivity and selectivity of compound 1 as luminescence probes for detecting CrO42−/Cr2O72− and a wide range of nitro aromatic compounds (NACs).
