A novel vitamin B6 Schiff base analog (L) was synthesized by combining vitamin B6 cofactor pyridoxal with 2-aminophenol. Receptor L displays a color change detectable by the naked-eye from yellow to red in the presence of fluoride and acetate due to the formation of hydrogen bonding host-guest complexes in 1 : 1 stoichiometry. Importantly, receptor L showed fluoride-selective 'turn-on' fluorescent response with a detection limit (3σ) of 7.39 × 10(-8) M.
一种新型维生素 B6 Schiff 碱类似物(L)由维生素 B6 辅因子吡哆醛与 2-氨基酚结合合成。受体 L 在氟离子和醋酸根存在下,由于形成 1:1 化学计量的氢键主体-客体配合物,表现出从黄色到红色的肉眼可见的颜色变化。重要的是,受体 L 对氟离子表现出选择性的“开启”荧光响应,检测限(3σ)为 7.39×10(-8) M。
