With the aid of a pyridyl tetracarboxylate ligand, 2,5-bis(2',5'-dicarboxylphenyl)pyridine (HL), two indium-organic frameworks, [In(L)(OH)]·2DMF·2HO () and [MeNH][In(L)]·2.5NMF·4HO (), with (6,8)- and (4,4)-connected nets have been constructed in different solvent systems. Both and exhibit high thermal and chemical stability. Gas sorption behavior of and for N, CH, CH, CO, and CH indicate excellent separation selectivities of CH/CH and CO/CH. Furthermore, possesses a high density of Brønsted sites and shows efficient catalytic conversion for CO cycloaddition with epoxides. Meanwhile, luminescence investigations reveal that can detect nitrofurazone efficiently.
在吡啶四羧酸配体的辅助下，合成了两种铟-有机框架化合物[In(L)(OH)]·2DMF·2H2O ()和[MeNH][In(L)]·2.5NMF·4H2O ()，其中 L 为 2,5-双(2',5'-二羧基苯基)吡啶。这两个化合物分别采用不同的溶剂体系，通过（6,8）-和（4,4）-连接模式构筑而成。化合物和均表现出良好的热稳定性和化学稳定性。对它们的气体吸附性能测试结果表明，这两个化合物对 CH/CH 和 CO/CH 的分离具有很好的选择性能。此外，化合物还具有高密度的 Brønsted 酸位，并对 CO 与环氧化合物的环加成反应表现出高效的催化转化性能。同时，荧光测试表明化合物能够对硝呋唑酮进行有效检测。
