Abstract
Two novel 2D bisthienoacenes with annulated thiophene units at different positions were developed. Both 1,2- and 1,4-addition of the α,β-unsaturated ketone moieties lead to the major formation of four-fold alkylsilylethynyl substituted 2D heteroacenes (namely BTT-4TIPS and BTP-4TIPS). The photophysical, electrochemical properties, crystal packing structures, and charge carrier transport performances were investigated in detail.
