Abstract

The reaction of In³⁺ ions with 2,5-di(2H-tetrazol-5-yl) terephthalic acid (H₄dtztp) affords a 3D indium-organic framework, [In(dtztp)_0.5(OH)(H₂O)]·H₂O (1) with a (3,6)-connected net. 1 shows good thermal (300 °C) and chemical stabilities (various organic solvents and acidic/basic solutions) and excellent water tolerance (7 days at room temperature or in boiling water). The acetylene (C₂H₂) sorption behavior of 1 indicates significant separation selectivity over CH₄, as confirmed by breakthrough experiments on the realistic gas mixtures. Meanwhile, the MOF with the Lewis and Brønsted acidic bifunctional catalytic sites catalyzes the CO₂ conversion with different epoxides with high yields. The fluorescent properties reveal the efficient probing performance of 1 for nitrofurantoin (NFT) and metronidazole (MDZ) in water with a low detection limit (ppm).
