Production of linear organic thiophene-phenylene oligomer comprises reacting dioxaborolane compound with an aromatic halide compound. Production of linear organic thiophene-phenylene oligomer of formula (I) comprises reacting a compound of formula (II) with a compound of formula Y-[Ar] m-Y, optionally in the presence of catalysts, optionally in a solution and optionally at an elevated temperature. [Image] m : 1-5; Ar : 1,4-phenylene or 2,7-fluorenylene optionally substituted with 1-20C alkyl residues, or with linear 1-20C alkyl residues interrupted by O; R 1>H, 1-20C alkyl interrupted by O, S, silylene, phosphonyl, phosphoryl, or 3-20C alkenyl; R A>, R B>H, 1-20C alkyl, 1-20C alkyl interrupted with 1-10 oxygen atoms, 1-20C alkoxy, and together form 1-6C dioxyalkylene ring; n : 2-4; Y : Cl, Br, I, or O-SO 2-R C>; and R C>phenyl, tolyl, methyl or trifluoromethyl. Independent claims are also included for: (1) a process for producing the compound of formula (II) comprising reacting a compound of formula (III) with a compound of formula (IV) (2) a semi-conductive coating comprising the organic thiophene-phenylene oligomer (I); (3) an article of manufacture comprising a coating layer comprising the organic thiophene-phenylene oligomer; (4) a process for producing the article of manufacture, comprising providing a substrate, and applying the coating composition to the substrate.
