title: Pi-Extended Diindole-Fused Azapentacenone: Synthesis, Characterization, and Photophysical and Lithium-Storage Properties.
abstract: 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.
