Abstract
The reaction of In 3+ ions with 2,5-di(2H-tetrazol-5-yl) terephthalic acid (H 4 dtztp) affords a 3D indium-organic framework, [In(dtztp) 0.5 (OH)(H 2 O)]·H 2 O ( 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 (C 2 H 2 ) sorption behavior of 1 indicates significant separation selectivity over CH 4, as confirmed by breakthrough experiments on the realistic gas mixtures. Meanwhile, the MOF with the Lewis and Brønsted acidic bifunctional catalytic sites catalyzes the CO 2 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).
