Herein, we describe the synthesis, structural diversity and diradicaloid characteristics of 38π core-modified aromatic expanded isophlorins with eight heterocyclic rings. The diradicaloid character of expanded isophlorinoid macrocycles was engineered by systematic structural modification. Depending on the nature of the link between the heteroatoms, they adopt planar and non-planar conformations. This large structural variation with a significant difference in the extent of aromaticity is correlated with the magnitude of their respective diradical character.
在此,我们描述了具有八个杂环的38π核心修饰的芳香族扩展异卟啉的合成、结构多样性和双自由基特征。通过系统的结构修饰来设计扩展异卟啉类大环的双自由基特征。根据杂原子之间连接的性质,它们呈现平面和非平面构象。这种具有显著芳香性差异的大结构变化与它们各自双自由基特征的大小相关。
