博士 === 國立臺灣大學 === 化學研究所 === 102 === Chapter 1 The efficient synthesis of asymmetrical rotaxanes with different macrocycles and stoppers remains to be a challenged task in the field of supramolecular chemistry. Recently, we report a solvent-free stoppering approach, which allows the efficient interlocking of few macrocycles in the form of [2]rotaxanes. Combining the concept of self-sorting, we plan to construct an asymmetrical [3]rotaxane, in which two macrocycles in different sizes are interlocked efficiently by their corresponding stoppers through a simple solvent-free reaction. Chapter 2 Recently, we demonstrated that the threading of oligo(ethylene glycol) units into bis-para-xylyl[26]crown-6 (BPX26C6) via Na+ ion template is possible. Herein, we reported that a macrocycle generated from a diamine and a dialdehyde can de “clipped” onto oligo(ethylene glycol) containing quests through the templating effect of a Na+ ion.
