Unsymmetrical heteroacenes, 11-phenylbenzofuro[3,2-b]carbazole (Ph-BFC) and its alkoxylated derivatives, were readily synthesized by palladium-catalyzed double N-arylation of arylamines. They characteristically form antiparallel cofacial pi-stacking arrangements, which may result from their unsymmetrical structures. Their physical properties show their potential for application as active layers in organic field-effect transistors.
不对称杂并苯、11-苯基苯并呋喃并[3,2-b]咔唑（Ph-BFC）及其烷氧基化衍生物，可通过钯催化芳基胺的双N-芳基化反应轻松合成。它们典型地形成反平行共面π-堆积排列，这可能源于其不对称结构。它们的物理性质显示出其作为有机场效应晶体管活性层的应用潜力。
