The inventions disclosed and described herein relate to new and efficient generic methods for making a wide variety of compounds having HAr - Z - Har tricyclic cores (II) from intermediates (I), wherein HAr is an optionally substituted five or six membered heteroaryl ring, and Hal is a halogen, and Z is a bridging radical, such as S, Sc, NRS, C(O), C(O)C(O), Si(R5)2, SO, S02, PRS, BRS, C(R5)2 or P(O)R5 and both HAr are covalently bound to one another. The synthetic methods employ a "Base-Catalyzed Halogen Dance" reaction to prepare a metallated compound comprising a five or six membered heteroaryl ring comprising a halogen atom, and then oxidatively coupling the reactive intermediate compound. The compounds of Formula (II) and/or oligomer or polymers comprising repeat units having Formula (IT) can be useful for making semi-conducting materials, and/or electronic devices comprising those materials. Acyl compounds can be prepared. Heteroary- lene substituents can be used. The core tricyclic core can be coupled to itself. The Z group also can be strong electron-withdrawing groups such as C=C(CN)2 or [C=C(CN)2]2. Organic electronic devices can be made including field-effect transistors. (Formula I, II)
本文所披露和描述的发明涉及一种新的高效通用方法,用于制备具有HAr-Z-Har三环核(II)的各种化合物,其来源于中间体(I),其中HAr是一个可选择取代的五元或六元杂环芳烃环,Hal是卤素,Z是桥接基团,如S、Sc、NRS、C(O)、C(O)C(O)、Si(R5)2、SO、S02、PRS、BRS、C(R5)2或P(O)R5,两个HAr均以共价键结合在一起。合成方法采用“碱催化卤素舞蹈”反应来制备包含卤素原子的五元或六元杂环芳烃环的金属化合物,然后氧化偶联反应中间体化合物。具有公式(II)的化合物和/或包含具有公式(IT)重复单元的寡聚物或聚合物可用于制备半导体材料,和/或包含这些材料的电子器件。可以制备酰基化合物。可以使用杂芳基取代基。核心三环核可以与自身偶联。Z基团也可以是强电子吸引基团,如C=C(CN)2或[C=C(CN)2]2。可以制造包括场效应晶体管在内的有机电子器件。(公式I,II)
