The charge neutral chiral optical sensors 1a-d containing thiourea and amide groups were synthesized by simple steps in good yields and their structures were characterized by IR, 1H NMR, 13C NMR, MS spectra and elemental analysis. The enantioselective recognition for alpha-phenylglycine and phenylglycinol was examined by fluorescence emission and UV-vis spectra. The fluorescence and UV-vis spectra changes of 1a were obvious when the enantiomers of alpha-phenylglycine anion were added, which exhibited that 1a has good enantioselective recognition ability towards alpha-phenylglycine.
含有硫脲和酰胺基团的电荷中性手性光学传感器1a - d通过简单步骤合成，产率良好，其结构通过红外光谱、1H核磁共振、13C核磁共振、质谱和元素分析进行表征。通过荧光发射和紫外可见光谱研究了对α - 苯甘氨酸和苯甘氨醇的对映选择性识别。当加入α - 苯甘氨酸阴离子的对映体时，1a的荧光和紫外可见光谱变化明显，这表明1a对α - 苯甘氨酸具有良好的对映选择性识别能力。
