A new fluorescent chemosensor based upon 2,5-diphenylfuran and 8-hydroxyquinoline was designed and synthesized. Its structure was confirmed by single crystal X-ray diffraction and its photophysical properties were studied by absorption and fluorescence spectra. This compound can be used to determine Fe3+ ion with high selectivity among a series of cations in aqueous DMF. This sensor forms a 1:1 complex
设计并合成了一种基于2,5-二苯呋喃和8-羟基喹啉的新型荧光化学传感器。通过单晶X射线衍射证实了其结构,并通过吸收和荧光光谱研究了其光物理性质。该化合物可用于在DMF水溶液中的一系列阳离子中以高选择性测定Fe 3+离子。该传感器与Fe 3+形成1:1的络合物并显示荧光猝灭。
