Pi ‐extended polyaromatics tend to exhibit improved electronic properties with respect to the intrinsic structures. Herein, the rational design of a π‐extended diindole‐fused diazapentacenone ( IP ), with a nine‐ring‐fused core, obtained by applying an intramolecular Friedel–Crafts diacylation synthetic routine, is reported. The chemical structure, physical properties, and morphology of IP were fully characterized. Serving as an organic cathode material for a lithium‐ion battery, the as‐prepared nanorods of π‐extended IP display higher conductivity and superior electrochemical performance than those of the naked diazapentacenone without diindole fusion.
