Abstract: Creating π-extended benzopentafulvalenes can aid development of novel functional materials for organic electronics. Herein, we describe a facile ring-expansion strategy to allow precise construction of benzopentafulvalenes in an asymmetric benzoannulation mode, which provides an unprecedented… read more here.
