The century-old yet synthetically underexplored anthracene photodimerization–cycloreversion reactions have been employed as the key steps to access highly strained aromatic hydrocarbons. Herein we report the chemical syntheses of oligoparaphenylene-derived nanohoops in five steps or less featuring a rigid dianthracene synthon. The newly synthesized nanohoops display intriguing experimental and computational properties.
