基于杯[4]芳烃的手性AIEgen用于酸及氨基酸的对映选择性识别OA

Two chiral AIEgens derived from calix[4]arene were synthesized,which exhibited prominent enantiose-lective 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 relation-ship between the chiral-dependent assembly behavior and the fluorescence response.
