Abstract

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. Abstract : 2D heteroacenes : Two stable 2D bisthienoacenes with eight or ten annulated aromatic rings were developed. The photophysical, electrochemical properties, crystal packing, and charge transport performance were investigated.
