Abstract: Herein, we report a methodology for constructing mechanically self-locked molecules (MSMs) through the efficient intramolecular copper(i)-catalyzed alkyne–azide cycloaddition (CuAAC) of self-threaded A1/A2-azido-propargyl-difunctionalized pillar[5]arenes. The obtained monomeric “pseudo[1]catenane” and dimeric “gemini-catenane” were isolated and fully characterized… read more here.

Abstract: A novel pillar[5]arene-based gemini-[1]rotaxane DEP5 was successfully designed and synthesized, the morphology and fluorescent properties of the gemini-[1]rotaxane DEP5 could be reversibly controlled by alternative addition of l-Arg and TFA. read more here.
