First, a nucleophilic bulky tertiary aniline interlocks a pseudorotaxane to form a surrogate rotaxane; this unit then functions as a leaving group for a set of bulky nucleophiles, affording rotaxanes with various linking functionalities, along with the bulky aniline recovered in its original form.en[SDGs]SDG3Sequential nucleophilic substitution of pseudorotaxanes forms rotaxanes with various linking functionalities and recycling of the surrogate stopperjournal article10.1039/d4cc02975e
