Supporting data for "nonalternant nanographenes containing nitrogen-doped nonhexagonal pairs: synthesis, structural analysis and photophysical properties"

Under the guidance of Scholl reaction, various nanographenes containg N-doped pentagon-heptagon pairs were synthesized in recent years. Due to the unexpected rearrangements and tedious synthetic routes toward nanographenes containg N-doped pentagon-heptagon pairs during Scholl reaction, the facile methodology is highly desired. Here we reported a series of novel nanographenes bearing N-doped pentagon-heptagon pairs through a facile ring expansion strategy. The resultant physicochemical properties could be fine-tuned through the modifications of heptagon spacers. Furthermore, diverse N-doped nanographenes containing heptagon-octagon pairs obtained from this ring expansion strategy demonstrated the high efficiency of the proposed method.

在Scholl反应的指导下，近年来合成了一系列含有N掺杂五边形-七边形对的纳米石墨烯。鉴于在Scholl反应过程中，含有N掺杂五边形-七边形对的纳米石墨烯在意外重排和繁琐的合成途径方面存在诸多不便，因此，一种简便的方法论备受推崇。本研究通过一种简便的环扩张策略，报告了一系列携带N掺杂五边形-七边形对的创新纳米石墨烯。通过调整七边形间隔基团的修饰，可以精细调节所得物质的物理化学性质。此外，从该环扩张策略中获得的含有七边形-八边形对的多种N掺杂纳米石墨烯，展示了所提出方法的显著高效性。
