【Abstract】 Two series of new ferrocene-bearing cyclo-pseudo-peptides, including three 1+1 type and three 2+2 type compounds, were designed and synthesized by liquid method. The interactions of the 1+1 type cyclo-pseudo-peptides as the host compounds with some anions were investigated by cyclic voltammetry(CV) and 1H NMR methods. The results show that the 1+1 type hosts can selectively interact with the guest anions by intermolecular hydrogen bond. A reasonable interaction model of the 1+1 type cyclo-pseudo-peptides with anions was proposed.更多还原
