A rotaxane (from Latin rota 'wheel', and axis 'axle') is a mechanically interlocked molecular architecture consisting of a dumbbell-shaped molecule which is threaded through a macrocycle (see graphical representation).
Aug 22, 2020 · In this chapter, we discuss the three transition steps in the evolution of rotaxanes, including novel synthetic methodologies, functionalization of rotaxane molecules, and immobilization of rotaxanes into solid-state or polymer substrates working as functional materials. This chapter is expected to promote the evolution of rotaxanes from their ...
Rotaxanes are mechanically interlocked molecules and contain one or more macrocycles threaded through a linear guest molecule. The macrocycles are trapped along the linear unit by the conjugation of stoppers that are larger than the macrocycle. A rotaxane resembles the shape of a dumbbell with a ring trapped in between the two ends (Fig. 13 ).
Oct 20, 2017 · This Minireview presents illustrative examples of chiral [2]catenanes and [2]rotaxanes, and discusses where these molecules have been used in chemical applications such as chiral host–guest recognition and asymmetric catalysis.

Apr 7, 2022 · Rotaxanes are an emerging class of molecules composed of two building blocks: macrocycles and threads. Rotaxanes, and their pseudorotaxane and polyrotaxane relatives, serve as prototypes for molecular-level switches and machines and as components in materials like elastic polymers and 3D printing inks.
Aug 16, 2021 · Inspired by the myriad enzymes found in living organisms, supramolecular chemists have investigated the cavities of both macrocycles and the related interlocked molecules catenanes and rotaxanes as catalytic and non-catalytic sites of chemical reactions.
Jun 10, 2019 · This minireview details advances in rotaxanes containing porphyrin, organized according to where the porphyrin is situated in the rotaxane structure. Specific examples are highlighted where the properties imparted to the structure by the porphyrin are uniquely utilized by the rotaxane architecture.
