摘　　要：This paper reports the synthesis of a perylene-bridged bis(crown ether) through the condensation reaction between primary amine-armed dibenzo-24-crown-8 and 3,4,9,10-perylenetetracarboxylic dianhydride.Pseudorotaxane with a perylene moiety at the wheel and a fullerene unit in the middle of the axle was prepared,which was evidenced by 1H NMR and fluorescence experiments.Subsequent investigations show that the formation and disassociation of the pseudorotaxane can be controlled by the alternating addition of KPF6 and 18-crown-6,following the change of the florescence intensity of perylene.This paper reports the synthesis of a perylene-bridged bis(crown ether) through the condensation reaction between primary amine-armed dibenzo-24-crown-8 and 3,4,9,10-perylenetetracarboxylic dianhydride.Pseudorotaxane with a perylene moiety at the wheel and a fullerene unit in the middle of the axle was prepared,which was evidenced by 1H NMR and fluorescence experiments.Subsequent investigations show that the formation and disassociation of the pseudorotaxane can be controlled by the alternating addition of KPF6 and 18-crown-6,following the change of the florescence intensity of perylene.
