Molecular recognition study on supramolecular system (Ⅲ)——Chiral recognition of aromatic amino acids by binuclear Cu(Ⅱ) complexes with cyclodextrins

The study of supramolecular species formed by the selective binding of substrate(guest) with a molecular receptor (host) is currently a signficant topic in chemistry,biochemistry, and so on. Natural and chemically modified cyclodextrins (CDs) having fairlyrigid and well-defined hydrophobic cavities can be taken as a molecular receptor to recog-nize a wide variety of organic, inorganic, and biological guest molecules, forming host-guestcomplexes or supramolecutar species, which have been applied to several areas of scienceand technology as an excellent model system mimicking the substrate-specific interaction of
