| Abstract: | Two ferrocenylmethyl ammonium salts were used as axle components of pseudorotaxanes with dibenzo24]crown‐8. The pseudorotaxane with an alkyne terminal group in the axle component underwent a Cu‐catalyzed Huisgen coupling reaction (click reaction) with an alkyl azide to afford cationic 2]rotaxanes with a triazole group in the axle molecule. The rotaxane reacted with Ac2O to produce neutral rotaxanes with an amide group in the axle component. Both cationic and neutral rotaxanes were treated with KPtCl3(CH2?CH2)] to form the PtII‐containing rotaxanes. |
