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 ...
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.
Jul 23, 2020 · We will classify the different examples based on the function of the rotaxane macrocycle in each specific case (vide infra), trying to shed light on the conceptual developments and the mechanistic details of the rotaxane-catalysts developed so far.

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.
