Abstract
The present invention relates to polyacene derivatives represented by general formula (I) below: (wherein Rto R, etc. each represents hydrogen atom, hydrocarbon group, or an alkoxy group; Aand Aare hydrogen atom, a halogen atom, a hydrocarbon group, an alkoxy group, cyano group, etc.; n is an integer of not less than 1; Rand Rmay be linked to each other to form a ring); and a process for preparing the polyacene derivatives from polyhydro compounds as well as electrically conductive materials comprising the polyacene derivatives. According to the process for preparing the polyacene derivatives of the present invention, optional substituents can be introduced into any carbon atoms of the polyacene, and the number of aromatic rings can be increased.
