Efficient Gas and VOC Separation and Pesticide Detection in a Highly Stable Interpenetrated Indium-Organic Framework.

The new indium-based organic framework {(MeNH)[In(BDPO)]·DMF·2HO} () was successfully constructed by using the oxalamide group modified ligand ,'-bis(isophthalic acid)oxalamide (HBDPO). This framework presents a 2-fold interpenetrating structural characteristic, and the unique polar pore environment leads to a high capture ability for CO, CH and CHOH and good separation ability for CO and CH over CH as well as for CHOH over CHOH, which was further verified by an ideal adsorbed solution theory (IAST) calculation. Theoretical simulations pointed out the possible adsorption sites of different adsorbed gases in . In addition, the excellent chemical stability and strong luminescence of give it an effective selective detection ability for 2,6-dichloro-4-nitroaniline (DCN) in water with a low detection limit of 3.85 ppm, and the detection mechanism is discussed in detail.
