NOVEL ADDUCT COMPOUND, METHODS FOR PURIFICATION AND PREPARATION OF FUSED POLYCYCLIC AROMATIC COMPOUND, SOLUTION FOR FORMATION OF ORGANIC SEMICONDUCTOR FILM, AND NOVEL -DIKETONE COMPOUND

摘要

Provided are a novel adduct compound and a novel ±-diketone compound, from which organic semiconductor layers consisting of a fused polycyclic aromatic compound can be formed by a solution method, said solution method being generally easier than a deposition method. Also provided are a method for the purification of the adduct compound, and a solution for the formation of organic semiconductor film, which contains the adduct compound. The adduct compound has a structure wherein a compound having a double bond is added in an eliminable state to a fused polycyclic aromatic compound of general formula (I): Ar 1 Ar 2 Ar 3 (I), while the ±-diketone compound has a structure wherein a compound having a double bond is added in an eliminable state to a fused polycyclic aromatic compound. The fused polycyclic aromatic compound is dinaphthothienothiophene or the like, while the compound having a double bond is hexachlorocyclopentadiene or the like. In general formula (I), Ar 1 , Ar 2 and Ar 3 are each as defined in the description.
