Beyond their aesthetic appeal, molecular links and knots are worthy synthetic targets that expand the chemist s repertoire of potential building blocks for engineering nanoscale devices.[1–8][2] Catenanes ([2] Cs), trefoil knots (TKs), and Solomon links (SLs) are three such idealized topologies that have been realized synthetically.[9] Although a wide variety of [2] Cs (mechanically interlocked molecules comprised of two macrocycles) have been ...
