Three new ferrocene based Schiff bases 4-{[(E)-ferrocenylmethylidene] amino}benzenethiol (1b), 3-{[(E)-ferrocenylmethylidene]amino} benzenethiol (1c), 2-{[(E)-ferrocenylmethylidene]amino} benzenethiol (1d) have been synthesized to study their sensor property to various metal ions. It has been observed that 1b is highly fluorescent and its fluorescence changes in presence of metal ions. It was further observed that compound 1b is highly selective towards Cd(2+) ion in solution.
三种新型基于二茂铁的席夫碱4-{[(E)-二茂铁基亚甲基]氨基}苯硫醇(1b)、3-{[(E)-二茂铁基亚甲基]氨基}苯硫醇(1c)、2-{[(E)-二茂铁基亚甲基]氨基}苯硫醇(1d)已被合成，用于研究它们对各种金属离子的传感性能。据观察，1b具有高荧光性，并且其荧光在金属离子存在下会发生变化。进一步观察到，化合物1b在溶液中对Cd(2+)离子具有高度选择性。
