Hydrothermal reaction of Cd2+ ions and 5-(4-carboxybenzyloxy)isoph-thalic acid (H3L) afforded a new 3D metal-organic framework (Cd-MOF), namely [Cd(HL)(2,2-bipy)](n)center dot 1.25nH(2)O. The luminescent properties of Cd-MOF dispersed in different solvents have been investigated systematically, demonstrating unique selectivity for the detection of CH2Cl2 via a fluorescence quenching mechanism. The luminescent intensity of Cd-MOF was selectively quenched by Ni2+ ions. (C) 2015 Elsevier B.V. All rights reserved.
