ABSTRACT:
An object of the present invention relates to provision of a terphenylene derivative having excellent oxidation resistance and capable of forming a semiconductor active phase by a coating process and an oxidation-resistant organic semiconductor material using the same, as well as an organic thin film.The invention relates to production of a terphenylene derivative represented by the formula (1) by tetralithiating a tetrahaloterphenyl derivative with a lithiating agent and subsequently treating the resulting compound with a copper compound:[ka 1]wherein R1to R14are the same or different and each represents a hydrogen atom, a fluorine atom, a chlorine atom, an aryl group having 4 to 30 carbon atoms, an alkynyl group having 3 to 20 carbon atoms, an alkenyl group having 2 to 30 carbon atoms, an alkyl group having 1 to 20 carbon atoms or a halogenated alkyl group having 1 to 20 carbon atoms, or a diarylamino group having 8 to carbon atoms; and l, m, and n each represents an integer of 0 or 1.
