N‐Acenoacenes: Synthesis and Solid‐State Properties

Chemistry – A European Journal, Volume 28, Issue 69, December 9, 2022., 2022
Enabling semiconducting properties in N‐acenoacenes. Reducing the steric demand of N‐acenoacenes tunes the solid‐state packings of N‐acenoacenes in favor of π–π‐stacking, allowing charge transfer through the crystal lattice. The first utilization of N‐acenoacenes in p‐type organic thin‐film transistors is reported.
