Defective nanographenes containing joined pentagons and heptagons exhibit striking physicochemical properties from both experimental and theoretical perspectives compared with their pure hexagonal counterparts. Thus, the synthesis and characterization of these unique polyarenes with well-defined defective topologies have attracted increasing attention. Despite extensive research on nonalternant molecules since the last century, most studies focused on the corresponding mutagenic and carcinogenic activities. Recently, researchers have realized that the defective domain induces geometric bending and causes electronic perturbation, thus leading to significant alteration of the photophysical properties. This review discusses the synthesis and characterization of small nonalternant polycyclic hydrocarbons in the early stage and recent developments in embedding pentagon–heptagon (5–7) pairs into large carbon skeletons through in-solution chemistry.

含有连接五边形和七边形的有缺陷的纳米石墨烯的合成



与纯六边形对应物相比,从实验和理论角度来看,含有连接的五边形和七边形的有缺陷的纳米石墨烯表现出惊人的物理化学性质。因此,这些具有明确缺陷拓扑的独特聚芳烃的合成和表征引起了越来越多的关注。尽管自上世纪以来对非交替分子进行了广泛的研究,但大多数研究集中在相应的诱变和致癌活性上。最近,研究人员意识到缺陷域会引起几何弯曲并引起电子扰动,从而导致光物理性质的显着改变。本文讨论了小型非交替多环烃的早期合成和表征,以及通过溶液化学将五边形-七边形(5-7)对嵌入大型碳骨架的最新进展。
