POLYACENE DERIVATIVES AND PROCESS OF PRODUCING THEREOF
The present invention relates to polyacene derivatives represented by general formula (I) below: (see formula I) (wherein R1 to R10, etc. each represents hydrogen atom, hydrocarbon group, or an alkoxy group
A1 and A2 are hydrogen atom, a halogen atom, a hydrocarbon group, an alkoxy group, cyano group, etc.
n is an integer of not less than 1
R6 and R7 may 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.
