A helical bilayer nonbenzenoid nanographene has been synthesized with a novel [10]helicene backbone bearing two heptagons. Single-crystal X-ray analysis revealed its highly twisted bilayer geometry with a small interlayer distance of 3.2 Å, in which the intramolecular through-space conjugation between the two layers is determined. Furthermore, the chiroptical properties of the P/M enantiomers of this helical nanographene have also been evaluated.

带有两个嵌入七边形的 [10] 螺旋烯的螺旋双层非苯类纳米石墨烯

合成了一种螺旋双层非苯类纳米石墨烯，其具有带有两个七边形的新型 [10] 螺旋烯主链。单晶 X 射线分析揭示了其高度扭曲的双层几何结构，层间距离很小，为 3.2 Å，其中确定了两层之间的分子内穿透空间共轭。此外，还评估了这种螺旋纳米石墨烯的P / M对映体的手性。
