摘要
Molecular recognition properties of chiral molecular tweezer s based on dexoycholic acid 1～4 for the aromatic amine have been investigated by UV-visi ble spectophotometric titration. The results showed that all these molecular twe ezers can form 1∶1 supramolecular complexes with aromatic amine. The recognizin g ability of these molecular tweezers come mainly from hydrogen bonding,π-π -stacking between aromatic residues and van der Waals interaction. The size / s hape-fit and geometrical complementary relationship between receptor and substr ate play a crucial role in the inclusion complexation of aromatic amines with re ceptor 1～4.
