Synthesis and Absorption Properties of Long Acenoacenes

Abstract Acenes, polyaromatic hydrocarbons composed of linearly fused benzene rings have received immense attention due to their performance as semiconductors in organic optoelectronic applications. Their appealing physicochemical properties, such extended delocalization, high charge carrier mobilities, narrow HOMO‐LOMO gaps and partially radical character the ground state make them very attractive targets for many potential However, intrinsic synthetic challenges unsubstituted members reactivity poor solubility are still limiting factors wider exploitation. Herein, we report a simple general synthesis new family angularly acenoacenes with improved stability compared isoelectronic linear counterparts. The comprehensive characterization pentacenopentacene, pentacenohexacene hexacenohexacene, lengths between decacene dodecacene, disclosed.
