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 ...
