A series of new chemosensor molecules bearing benzothiazole-, quinoline- and phthalazine-functionalized fluorene derivatives were synthesized and their complexation behaviors with Fe and Sn ions were investigated. The sensing abilities of their complexes towards both cyanide and sulfide anions were investigated by colorimetric and fluorometric techniques in detail. The sensing mechanism was investigated by Job's and Scatchard plots evaluations, and also absorption/fluorescence titration experiments. Among the studied dye/metal binary systems, F-BT sensor to Fe giving the detection limits of 3.1 µg has also displayed high selectivity and sensitivity towards CN and S anions, lead to a significant color change of the solution observable by the naked eye.
一系列含有苯并噻唑、喹啉和邻苯二甲酰亚胺官能化芴衍生物的新型化学传感器分子被合成，并研究了它们与 Fe 和 Sn 离子的络合行为。通过比色和荧光技术详细研究了它们的络合物对氰化物和硫化物阴离子的传感能力。通过 Job 和 Scatchard 图谱评估以及吸收/荧光滴定实验研究了传感机制。在所研究的染料/金属二元体系中，F-BT 传感器对 Fe 的检测限为 3.1µg，对 CN 和 S 阴离子也表现出高选择性和灵敏度，导致溶液发生明显的肉眼可见的颜色变化。
