摘要
New chiral molecular tweezers 1～3 were designed and synthesized by using deoxycholic acid as spacer. Their structures were confirmed by IR, 1HNMR and elemental analysis. The recognition properties were investigated by UV Vis spectra titration in CHCl 3 at 25℃. The results indicated that molecular tweezers 1～3 possess the ability to complex with aromatic amine. The size/shape fit and geometric complementary relationship between receptor and substrate play the key roles in recognition process.
