      Abstract:

      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 cm2/(V s).
