Design and Synthesis of Paraphenylene-derived Figure-of-eight Rigid Macrocycles

Macrocycles are essential building blocks for supramolecular architectures. In this Highlight Review, recent progress in our laboratory is summarized regarding the development of paraphenylene-derived figure-of-eight rigid macrocycles. These molecules are derived from X-shaped cores including anthracene photodimer, tetraphenylethylene, and copper-phenanthroline complex, and exhibit attractive topological or fluorescent properties.
