of strategically designed boronic acid containing fluorescent sensors, o-, m-, p-BMOQBA, for the potential detection of tear glucose concentrations when immobilized in plastic disposable contact lenses is described. The new probes, BMOQBAs, consist of the 6-methoxyquinolinium nucleus as a fluorescent indicator, and the boronic acid moiety as a glucose chelating group. A control compound BMOQ, which has
描述了精心设计的含硼酸荧光传感器 o-、m-、p-BMOQBA 的合成、表征和光谱特性,用于固定在塑料一次性隐形眼镜中时潜在检测泪液葡萄糖浓度。新探针 BMOQBA 由作为荧光指示剂的 6-甲氧基喹啉鎓核和作为葡萄糖螯合基团的硼酸部分组成。还制备了对照化合物 BMOQ,其不具有硼酸基团,因此不结合单糖。在本文中,我们表明新探针的结构设计考虑因素保证了它们在镜片内的兼容性,降低的探针糖结合 pK(a) 有利于弱酸性镜片环境。此外,新探针易溶于水,具有高量子产率,并且可以通过简单的一步合成程序制备。
