A series of new chemosensor molecules bearing benzothiazole-, quinoline- and phthalazine-functionalized fluorene derivatives were synthesized and their complexation behaviors with Fe3+ and Sn2+ ions were investigated. The sensing abilities of their complexes towards both cyanide and sulfideanions were investigated by colorimetric and fluorometric techniques in detail. The sensing mechanism was investigated
合成了一系列带有苯并噻唑、喹啉和酞嗪功能化的芴衍生物的新型化学传感器分子,并研究了它们与Fe 3+和Sn 2+离子的络合行为。通过比色和荧光技术详细研究了它们的配合物对氰化物和硫化物阴离子的传感能力。通过 Job 和 Scatchard 图评估以及吸收/荧光滴定实验研究了传感机制。在研究的染料/金属二元系统中,F-BT传感器对 Fe 3+的检测限为 3.1 µ g,也显示出对 CN -和 S 的高选择性和灵敏度2−阴离子,导致肉眼可观察到的溶液显着的颜色变化。
