A Series of Soluble Thieno-fused Coronene Nanoribbons of Precise Lengths [Data]

Among graphene nanoribbons (GNRs), reports on coronene-based GNRs were very rare, despite the unique optoelectronic properties of coronene. Herein, the synthesis of a series of structurally precise and soluble thieno-fused coronene nanoribbons (CR-1 to CR-4) with up to four coronene units connected through benzene rings along their K-regions is described by two different synthetic approaches. Due to the triptycene end-caps all CRs are highly soluble, allowing to characterize such structures in solution and study the length dependent photophysical properties which are supported by theoretical calculations.
