HETEROACENE DERIVATIVE, TETRAHALOTERPHENYL DERIVATIVE, AND THEIR PRODUCTION METHODS

There are provided a heteroacene derivative having an 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. [Means for Resolution] heteroacene derivative represented by the formula (1) is obtained by tetrametalation of a tetrahaloterphenyl derivative with a metalation agent and subsequent treatment of the resulting compound with reaction agents: wherein the substituents R1 to R4 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 alkyl group having 3 to 20 carbon atoms, or a halogenated alkyl group having 1 to 20 carbon atoms; T1 and T2 are the same or different and each represents sulfur, selenium, tellurium, oxygen, phosphorus, boron, or aluminum; 1 and m each is an integer of 0 or 1; and rings A and B are the same or different and each has a structure represented by the following formulae (A-1) or (A-2).

TERPHENYLENE DERIVATIVES, TETRAHALOTERPHENYL DERIVATIVES AND PROCESSES FOR THE PRODUCTION OF BOTH

The invention provides terphenylene derivatives which have excellent oxidation resistance and permit the formation of semiconductor active phases by coating; and oxidation-resistant organic semiconductor materials and organic thin films, made by using the same. The invention relates to production of terphenylene derivatives represented by the general formula (1) by tetralithiating a tetrahaloterphenyl derivative with a lithiating agent and then treating the obtained compound with a copper compound: (1) wherein R1 to R14 are each independently hydrogen, fluoro, chloro, aryl having 4 to 30 carbon atoms, alkynyl having 3 to 20 carbon atoms, alkenyl having 2 to 30 carbon atoms, alkyl having 1 to 20 carbon atoms, halogenated alkyl having 1 to 20 carbon atoms, or diarylamino having 8 to 30 carbon atoms; and l, m, and n are each an integer of 0 or 1.
