Abstract
AbstractIntroduction of non‐hexagons and/or heteroatoms allows for finely tuning the physicochemical properties of nanographenes. Heteroatoms doping have dominated the modulation of nanographenes with tunable band gap, rich electrochemical activities and so on. The pair of non‐hexagons, for instance, pentagon‐heptagon pairs, have furnished nanographenes with aromatic and/or antiaromatic characteristics, open‐shell properties and so on. In order to meet the growing demand for versatile nanographenes in materials science, research on novel nanographenes with heteroatom doped non‐hexagonal pairs has been aroused in recent years. In this review, we focus on nanographenes with nitrogen‐doped non‐hexagonal paris including the synthesis, structure analysis, photophysical properties, and potential applications in organic devices.
