A novel braided hetero[2](3)rotaxane is demonstrated by integrating the braided structure and mechanically interlocked rotaxane, in which a heterotritopic linear tris(dialkylammonium) guest penetrates a heterotritopic tris(crown ether) host, resulting in the formation of braided pseudohetero[2](3)rotaxane with different crossing and threading points. Then a braided hetero[2](3)rotaxane is constructed through the "CuAAC" click reaction.
