<p>Polyacene derivatives of the general formula (I); a process for preparing the derivatives from polyhydro compounds; and electrically conductive materials containing the derivatives: In said formula (I) R?1 to R10¿ are each hydrogen, hydrocarbyl, or alkoxy; A?1 and A2¿ are each hydrogen, halogeno, hydrocarbyl, alkoxy, cyano, or the like; and n is an integer of 1 or above, or alternatively R?6 and R7¿ may form a ring. According to the process, arbitrary substituents can be introduced into polyacene at arbitrary carbon atoms to increase the number of fused aromatic rings.</p> |
