摘要：A new metal-organic framework, namely [Cu4I(TIPE)(3)]center dot 3I (1) (TIPE = tetra(3-imidazoylphenyl)ethylene), has been synthesized in the presence of sulfosalicylic acid under hydrothermal condition. Single-crystal X-ray diffraction shows that compound 1 exhibits a 2-nodal (4, 12)-connected interpenetrating network. Its luminescent property has been investigated at room temperature. Moreover, it has been used to detect halogen ions, and the experimental results show that it can selectively sense F- ions through fluorescence quenching. The detection limit towards F- ions is calculated to be 2.11 x 10(-6) mol/L. (C) 2015 Elsevier B.V. All rights reserved.
