Introduction of nonhexagons and/or heteroatoms allows for finely tuning the physicochemical properties of nanographenes. Heteroatoms doping have dominated the modulation of nanographenes with tunable bandgap, rich electrochemical activities and so on. The pair of nonhexagons, 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 nonhexagonal pairs has been aroused in recent years. In this review, we focus on nanographenes with nitrogen‐doped nonhexagonal paris including the synthesis, structure analysis, photophysical properties, and potential applications in organic devices.

带有氮掺杂非六方对的非交替纳米石墨烯：合成、结构分析和光物理性质


非六边形和/或杂原子的引入可以微调纳米石墨烯的物理化学性质。杂原子掺杂主导了纳米石墨烯的调制，具有带隙可调、丰富的电化学活性等。非六边形对，例如五边形-七边形对，使纳米石墨烯具有芳香和/或反芳香特性、开壳特性等。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，人们开始研究杂原子掺杂非六方对的新型纳米石墨烯。在这篇综述中，我们重点关注具有氮掺杂非六方巴黎的纳米石墨烯，包括合成、结构分析、光物理性质以及在有机器件中的潜在应用。
