Title:
ターフェニレン誘導体、テトラハロターフェニル誘導体及びそれらの製造方法
Document Type and Number:
Japanese Patent JP5061896
Kind Code:
B2
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 R 1 to R 14 are 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 30 carbon atoms; and 1, m, and n each represents an integer of 0 or 1.
