Relationship in supramolecular systems between the substrate and the receptor, is corresponding in complexes relationship between the central metal ion and the ligand. This academic papers presented a new concept “enzyme - like ligand” was “such as an enzyme as the ligand”, The intermolecular forces of the supramolecular are noncovalent bonds. It is widely applied in bio- materials and biomemetic polymers. The oligo- peptide of prolines being linked, the 3 in 4 of sec-amino of prolines to contain amido, came into tert-amino. The proline oligopeptides were fixed by acrylic acid polymer nanofilms as chiral stationary phase and AFM imaging observations were used for the enzyme - like ligand films by discussion. Glucosan derivate BifCTS was used as the selector for metal cations. The derivate grafted onto Sigel to form Sigel-g-BifCTS， Abbreviated SiBiCS. Adsorption and recognition for Cu2+, Cd2+, Fe2+, Fe3+ by SiBiCS and isothermal adsorption equilibrium curve of Cu2+ were investigated. |
