The synthesis of three heptacyclic heteroacenes is described, namely anthra[2,3-b:7,6-b']bis[1]benzothiophenes (ABBTs). A stepwise sequence of aldol reactions provides regiochemical control, affording only the syn-isomer. The ABBTs are characterized by X-ray crystallography, UV-vis absorption, and emission spectroscopy, as well as cyclic voltammetry. Field effect transistors based on solution-cast thin films of ABBT derivatives exhibit charge-carrier mobilities of as high as 0.013 cm(2)/(V s).
本文描述了三种七元杂并苯并噻吩的合成，即蒽[2,3-b:7,6-b']并[1]苯并噻吩（ABBTs）。通过逐步的羟醛缩合反应可以实现区域化学控制，仅得到顺式异构体。ABBTs 的结构通过 X 射线晶体学、紫外-可见吸收光谱和发射光谱以及循环伏安法进行了表征。基于 ABBT 衍生物溶液浇铸薄膜的场效应晶体管表现出高达 0.013 cm(2)/(V s)的电荷载流子迁移率。
