Introduction 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.
引入非六边形和/或杂原子有助于精细调节纳米石墨烯的物理化学性质。杂原子掺杂在调控具有可调带隙、丰富电化学活性等的纳米石墨烯方面占据主导地位。例如，一对非六边形，即五角形-七角形对，赋予了纳米石墨烯芳香和/或反芳香特性、开壳性质等。为了满足材料科学中对多功能纳米石墨烯不断增长的需求，近年来对具有杂原子掺杂非六边形对的新型纳米石墨烯的研究兴起。在本综述中，我们聚焦于具有氮掺杂非六边形对的纳米石墨烯，包括其合成、结构分析、光物理性质以及在有机器件中的潜在应用。
