Two chiral colorimetric sensors (1,2) were synthesized and characterized by spectroscopic techniques and their enantioselective recognition of chiral dicarboxylic anions (D/L-aspartate and D/L-malate) was examined by UV-vis and 1H NMR spectroscopy. Interaction of the receptors 1 and 2 with the enantiomers of aspartate or malate caused different color changes, and they act as optical chemosensors for
合成了两个手性比色传感器(1,2),并通过光谱技术对其进行了表征,并通过紫外可见光谱和1 H NMR光谱对它们的手性二羧酸阴离子(D / L-天冬氨酸和D / L-苹果酸)进行对映选择性识别。受体的相互作用1和2与天冬氨酸或苹果酸的对映异构体不同而引起的颜色变化,以及它们作为光学化学传感器用于识别d天冬氨酸与大号天冬氨酸和d -苹果与大号-苹果。受体1对天冬氨酸阴离子具有高对映选择性结合[ KA (D) / KA (L) = 12.15]。
