Construction of a tetrabenzotetrathia[8]circulene by a “fold-in” oxidative fusion reaction: synthesis and optical properties

Abstract

Herein we report the first synthesis of a tetrabenzotetrathia[8]circulene by a “fold-in” type oxidative fusion reaction. Compared to the pristine tetrathia[8]circulene, the four-fold benzoannulation slightly weakened the antiaromatic character of the central COT ring. The tetrabenzotetrathia[8]circulene exhibited fluorescence at room temperature, and phosphorescence at 77 K with a phosphorescence quantum yield of 11.7%.
