A very stable Zn-II-organic framework, {[Zn(Titpe)(0.5)(bpodc)]center dot(H2O)(3)}(n) (1, Titpe = 1,1,2,2-tetrakis(4-(imidazol-1-yl)phenyl)ethane, bpodc = benzophenone-4,4-dicarboxylic acid), has been synthesized under hydrothermal conditions. Single-crystal X-ray analysis reveals that 1 crystallizes in the monoclinic system and P(2)1/c space group. Its overall structure is a 3-D stacking with a porosity of 20.95% and a 4-c type topological network; it shows good stability in many solvents. Studies of the solution-phase detection of metal cations show that Fe3+ and Cr3+ ions can quench luminescent emission of 1. Fluorescence titration experiments show that 1 is more selective to Fe3+ (K-sv = 2.8 x 10(4) M-1) than Cr3+ (K-sv = 1.4 x 10(3) M-1). The solution-phase detection for anions by 1 also show high selectivity and sensitivity for Cr2O72- anions (K-sv = 1.2 x 10(4) M-1). With water stability and strong blue luminescence, 1 can potentially apply as a reversible multi-responsive luminescence sensor for Fe3+, Cr3+, and Cr2O72- in aqueous solutions.
