摘要
A ditopic macrocycle with a bisamide and a half dibenzo-crown ether component has been newly synthesized and its complexation behavior toward neutral phenanthroline derivatives is reported. The macrocycle can bind phenanthroline derivatives very strongly by hydrogen bonding and pi-electron interaction, yielding pseudorotaxane structures. The inclusion complexes show a pH controllable reversible threading-dethreading molecular switching system.
