A series of polyfused aromatics containing coronene and perylene in their frameworks was successfully constructed by a modified Ramirez–Corey–Fuchs reaction as the key reaction. Typical six-membered annulation and atypical five-membered annulation through controlled reaction conditions led to a range of extensively conjugate aromatics as possible candidates for organic semiconductors. A significant p-type field-effect mobility of 0.42–0.64 cm2/V·s was obtained from one of the derivatives, dibenzo[a,d]coronene.
