acid compounds (1-4) were synthesized. The effect of various carbohydrates on their fluorescence properties has been studied in aqueous phosphate buffer at pH 7.4. Different substitutions on the aniline group of the naphthalene ring resulted in significant differences in fluorescence properties for these four compounds. Compound 1 shows ratiometric fluorescence changes upon addition of a sugar. Compounds
合成了四种新的萘基硼酸化合物(1-4)。在pH 7.4的磷酸盐水溶液中研究了各种碳水化合物对其荧光性质的影响。萘环的苯胺基上的不同取代导致这四种化合物的荧光性质显着不同。化合物1在添加糖后显示出比例荧光变化。化合物2和3不会显示比例荧光变化,但会显示非常大的荧光强度变化(荧光强度增加约70倍)。除了添加糖后可量化的荧光性质变化外,肉眼还可以看到1-3的荧光颜色变化。然而,
