The ratiometric fluorescent sensor based on furoquinoline has been designed and synthesized, and not only exhibits a large Stokes shift of 199 nm in a mixture of C(2)H(5)OH-H(2)O (v/v = 8 ratio 2, 10 mM Tris-HCl, pH = 7.3), but can selectively detect zinc ions in the presence of competing metal ions with a red-shift of 75 nm; moreover, cell stain experiments show that can readily reveal a change in
设计并合成了基于呋喃喹啉的比例荧光传感器,它不仅在C(2)H(5)OH-H(2)O(v / v = 8比率)的混合物中表现出199 nm的大斯托克斯位移2,10 mM Tris-HCl,pH = 7.3),但可以在存在竞争性金属离子且红移75 nm的情况下选择性检测锌离子;此外,细胞染色实验表明,可以很容易地揭示细胞内Zn(2+)的变化。
