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] A 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 R
1
to R
4
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; T
1
and T
2
are the same or different and each represents sulfur, selenium, tellurium, oxygen, phosphorus, boron, or aluminum; l 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).
