摘要

A new lanthanide metal-organic framework (MOF)[Eu(BTB)(phen)(DMF)]·DMF (1,DMF =N,N-dimethylformamide) was synthesized using H3BTB (1,3,5-tri(4-carboxyphenyl)benzene) and phen(1,10-phenanthroline) under solvothermal conditions.The structure of the prepared MOF was characterized by single-crystal X-ray diffraction analyses,elemental analysis,fluorescence spectrum,FT-IR spectroscopy,powder X-ray diffraction and thermogravimetric analyses.The structure of 1 can be viewed as a 3-D supramolecular network,which is formed by the stacking of 2D layers through π-π interaction.The luminescence explorations revealed that 1 possesses favorable selectivity and sensitivity for testing Fe3+.Additionally,color tuning was achieved by varying Eu3+∶Tb3+ ratios in the reaction mixtures.
