    “…A tetrathiafulvalene (TTF)-containing crown ether macrocycle with C(s) symmetry was designed to implement planar chirality into a redox-active [2]rotaxane. The directionality of the macrocycle atom sequence together with the non-symmetric axle renders the corresponding [2]rotaxane mechanically planar chiral. …”

    “…Extension of this strategy via coupling of two prerotaxanes bearing complementary linker functionalities (i.e., azide and alkyne) and follow-up attachment of stopper groups provide efficient access to [n]rotaxanes. The applicability and modular nature of this novel approach were demonstrated by the synthesis of a series of [2]-, [3]-, and [4]rotaxanes. …”

    “…Reported herein are studies using one of the largest macrocycles reported to date to synthesize doubly threaded [3]rotaxanes. A large ditopic 46 atom macrocycle containing two 2,6-bis(N-alkyl-benzimidazolyl)pyridine ligands has been used to synthesize several metastable doubly threaded [3]rotaxanes in high yield (65–75% isolated) via metal templating. …”
