摘要
以5-取代间苯二甲酸和4,4′-联吡啶为混合配体,与硝酸钴在水热条件下合成了4个钴配合物。其中取代基是甲基(配合物3)和甲氧基(配合物4)时,合成的配合物具有相似的结构,并且二者的热稳定性较好。考察了配合物1~4对二氧化碳和乙炔的吸附性能,结果表明配合物4具有较好的吸附性能。此外,荧光性能分析表明配合物3对Al 3+、Fe 3+具有选择性检测能力。
Using 5-substituted isophthalic acid and 4,4′-bipyridine as mixed ligands,four cobalt complexes were synthesized under hydrothermal conditions.When the substituents were methyl(complex 3)and methoxy(complex 4),the synthesized complexes had similar structure,and their thermal stability were better.The adsorption properties of complexes 1~4 to carbon dioxide and acetylene were investigated,and the results showed that complex 4 had better adsorption properties.In addition,the results of fluorescence analysis showed that complex 3 had selective detection ability for Al 3+or Fe 3+.
