Patent ID: 8236998

Claim:
A method for producing a polyacene compound from a polyacenequinone compound by two reaction steps comprising: a first reaction step of reducing a polyacenequinone compound into a hydroxypolyacene derivative, and a second reaction step of halogenating and aromatizing the hydroxypolyacene compound into a polyacene compound having a structure represented by the chemical formula (I), wherein the polyacenequinone compound has a chemical structure corresponding to that of the polyacene compound, has the same number of 6-membered rings and the same R 1 , R 2 , R 3 and R 4 , and has the carbonyl carbon of quinine, the carbon atom of which will be bound to a halogen group, when it is converted into the polyacene compound, and the hydroxypolyacene compound has a chemical structure corresponding to that of the polyacene compound, has the same number of 6-membered rings and the same R 1 , R 2 , R 3 and R 4 , and has a carbon atom bound to a hydroxyl group and hydrogen atom, which will be bound to a halogen group, when it is converted into the polyacene compound, wherein at least one of R 1 , R 2 , R 3 and R 4 in the chemical formula (I) is/are an alkyl group having 1 to 15 carbon atoms or an alkoxy group having 1 to 15 carbon atoms, and the other(s) is/are a hydrogen atom; wherein two of Xs are each a halogen group and bound to the same acene ring and the others are each a hydrogen atom; and wherein k is an integer of 1 to 5.
