Title: AROMATIC COMPOUND, ORGANIC SEMICONDUCTOR LAYER, AND ORGANIC THIN FILM TRANSISTOR
Abstract:
Provided are: a novel aromatic compound which serves as a coatable organic semiconductor material that has high carrier mobility, high heat resistance and adequate solubility; an organic semiconductor layer which uses this aromatic compound; an organic thin film transistor; and a method for producing a novel aromatic compound. An aromatic compound which is represented by general formula (1-I) or (1-II). (In the formulae, A represents a covalent bond, an oxygen atom, a sulfur atom, a selenium atom, NR14 or CR15=CR16; A1 represents CR3=CR4, an oxygen atom, a sulfur atom or a selenium atom; A2 represents CR7=CR8, an oxygen atom, a sulfur atom or a selenium atom; A3 represents CR5=CR6, an oxygen atom, a sulfur atom or a selenium atom; among the combinations of adjacent two moieties of R1-R8 moieties, one to three combinations form a monocyclic to fused tetracyclic ring, and all rings constituting the monocyclic to fused tetracyclic ring are four-membered to six-membered rings; each of the other moieties of the R1-R8 moieties, which does not constitute the monocyclic to fused tetracyclic ring, independently represents a hydrogen atom, a halogen atom, an alkyl group having 1-20 carbon atoms, an alkenyl group having 2-20 carbon atoms, an alkynyl group having 2-20 carbon atoms, an alkadienyl group having 4-22 carbon atoms, an alkadiinyl group having 4-22 carbon atoms or an aryl group having 4-26 carbon atoms; and each of R14-R16 moieties independently represents a hydrogen atom, a halogen atom, an alkyl group having 1-20 carbon atoms, an alkenyl group having 2-20 carbon atoms, an alkynyl group having 2-20 carbon atoms, an alkadienyl group having 4-22 carbon atoms, an alkadiinyl group having 4-22 carbon atoms or an aryl group having 4-26 carbon atoms.)
