Rational synthesis, spectroscopic and solid-state structural isolation of an unprecedented core modified N-confused fused porphyrinogen 7 as a single isomer has been achieved in near quantitative yield. The solid-state crystal structure reveals a non-planar structure as a result of four sp³ meso carbons for 7. All possible stereoisomers of the S₂N₃ hybrid N-confused fused porphyrinogen 7 have been unravelled via DFT studies. The genesis of the porphyrinogen-porpho(mono/di)methene-porphyrin skeleton rearrangements has been unravelled using controlled chemical oxidation methods. The σ and π (anti)aromaticity of the porphyrinoids 9 and 10 have been thoroughly investigated via spectroscopic and in-depth DFT studies.

核心修饰的 N-混淆稠合卟啉原的 X 射线表征和 π(σ) (反)芳香族 N-混淆稠合卟啉类化合物的起源

以接近定量的产率实现了前所未有的核心修饰的 N-混淆稠合卟啉原 7 作为单一异构体的合理合成、光谱和固态结构分离。由于 7 有四个 sp ³ 内消旋碳，固态晶体结构显示出非平面结构。 S ₂ N ₃ 杂合 N 混淆的融合卟啉原 7 已通过 DFT 研究揭开。使用受控化学氧化方法已经阐明了卟啉原-卟啉（单/二）亚甲基-卟啉骨架重排的起源。类卟啉 9 和 10 的 σ 和 π（反）芳香性已通过光谱和深入的 DFT 研究进行了彻底研究。
