Regioisomeric Control of Charge Transport Properties in Fluoranthene-Fused 12-Ring Heteroarenes.

ABSTRACT: Heteroarene-based organic semiconductors (OSCs) have emerged as promising material candidates for large-area, flexible electronic and photonic devices due to their favorable π-conjugation systems and tunable optoelectronic properties. However, their development is still hindered by synthetic and design challenges, in particular, the limited access to highly polycyclic heteroarenes with tunable properties and the unexplored effects of topological isomerism. Here, we have successfully synthesized three regioisomeric thienoacenes (BTFA4-6) by fusing a dicyanofluoranthene unit, which have an identical 12-fused ring composition but different molecular topologies with [a] or [c]-fusion and syn or anti-CN substitution. We demonstrate that solution-processable BTFA4-6 exhibits
