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.

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is more stable,...

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...
