Functional Rotaxanes: From Synthetic Methodology to Functional Molecular Materials

Abstract

Rotaxanes, members of the family of mechanically interlocked molecules, have attracted much attention in the last decades. Remarkable efforts have been put into the development of their syntheses and functionalizations, making rotaxanes a promising class of compounds in versatile materials applications. 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 synthesis and functionalization in solution toward functional solid-state materials and devices.
