摘要：

A water stable tetrazolate-containing metal-organic framework, [Cd-2(L)(OH)(H2O)(2)](n) (1) [H3L = 5-(4-(tetrazol-5-yl)phenyl)isophthalic acid], was synthesized under solvothermal conditions and structurally characterized. Compound 1 displays a three dimensional porous network with one dimensional tubular channels based on trinuclear cluster [Cd-3(mu(3)-OH)N4C] units. Notably, 1 exhibits highly sensitive response to Cu2+ and Cr2O72- through luminescence quenching effects with the detection limit of 0.666 ppm for Cu2+ and 0.846 ppm for Cr2O72-, respectively. The possible mechanism of the luminescence quenching was discussed in detail.
