Selective Chiral Symmetry Breaking and Luminescent Sensing of Zn(II) Metal-Organic Framework

Abstract

The chiral Zn(II) metal-organic framework of [(CH3)2NH2]5[Zn1.5(Zn3O)(TATAT)2]•9DMF•17H2O (1) has been prepared from achiral precursors Zn(NO3)2•6H2O and 5,5’,5’’-(1,3,5-triazine-2,4,6-triyl)tris(azanediyl)triisophthalate (H6TATAT) in a mixture solvent of DMF/MeOH/H2O/HCOOH without chiral source. In particular, the nonrandom handedness excess (1P >> 1M) was generated and was verified by single-crystal X-ray diffraction and solid-state circular dichroism spectroscopy. Furthermore, complex 1 displays high selectivity and sensitivity for detection Fe3+ and is found to be an excellent chemical sensor of detecting nitro explosives especially for 3-nitrophenol.
