Abstract

Abstract : A water stable tetrazolate‐containing metal‐organic framework, [Cd2 (L)(OH)(H2 O)2 ] n (1 ) [H3 L = 5‐(4‐(tetrazol‐5‐yl)phenyl)isophthalic acid], was synthesized under solvothermal conditions and structurally characterized. Compound1 displays a three dimensional porous network with one dimensional tubular channels based on trinuclear cluster [Cd3 (μ3 ‐OH)N4 C] units. Notably, 1 exhibits highly sensitive response to Cu 2+ and Cr2 O7 2– through luminescence quenching effects with the detection limit of 0.666 ppm for Cu 2+ and 0.846 ppm for Cr2 O7 2–, respectively. The possible mechanism of the luminescence quenching was discussed in detail. Abstract :
