Giant Star‐Shaped Nitrogen‐Doped Nanographenes

Giant stars! A new family of giant star‐shaped N‐doped nanographenes (SNGs) with diameters up to 6.5 nm is reported. The SNGs are highly soluble in neutral organic solvents at room temperature, which allowed a complete structural, optoelectronic, and electrochemical characterisation.

Abstract

Star‐shaped nanographenes (SNGs) are large monodisperse polycyclic aromatic hydrocarbons that are larger than a nanometer and have shown a lot of promise in a wide range of applications including electronics, energy conversion, and sensing. Herein, we report a new family of giant star‐shaped N‐doped nanographenes with diameters up to 6.5 nm. Furthermore, the high solubility of this SNG family in neutral organic solvents at room temperature allowed a complete structural, optoelectronic, and electrochemical characterisation, which together with charge transport studies illustrate their n‐type semiconducting character.
