摘要:

合成了两种基于杯[4]芳烃的手性AIEgen, 该分子表现出显著的对映体选择性识别能力. 实验结果表明, 它们能够高效区分12种手性酸及氨基酸, 其中与D-丝氨酸和L-丝氨酸作用后, 体系的荧光强度比高达约42, 展现出优异的手性识别性能. 采用扫描电子显微镜(SEM) 对识别前后体系的形貌进行了表征, 发现不同对映体诱导形成了不同的形态结构, 揭示了手性依赖的组装行为与荧光响应之间的内在关联.

Abstract:

Two chiral AIEgens derived from calix[4]arene were synthesized, which exhibited prominent enantioselective recognition capabilities. Experimental results demonstrated that these AIEgens could efficiently discriminate between 12 types of chiral acids and amino acids. Notably, upon interaction with D-serine and L-serine, the fluorescence intensity ratio of the system reached 42.0, indicative of exceptional chiral recognition performance. The morphologies of the systems before and after identification were characterized using scanning electron microscopy(SEM). It was found that different enantiomers induced distinct morphological structures, revealing the intrinsic relationship between the chiral-dependent assembly behavior and the fluorescence response.
