and the original scaffold of PyTeAP was confirmed by single-crystal X-ray diffraction analysis of one derivative. Examination of their photophysicalproperties in solution revealed blue fluorescence with λem = 416–426 nm. Theoretical investigations of the aromaticity in these compounds through magnetic criteria evidenced the presence of a dominant 14-electron circuit at the periphery.
吡嗪稠合 1,2,6,6a-四氮杂戊二烯 (PyTeAP) 是两性离子三环化合物,具有四个连续氮原子的原始模式。它们是通过在热解条件下形成 N-N 键通过具有挑战性的环化获得的。合成了十种衍生物,并通过一种衍生物的单晶 X 射线衍射分析证实了 PyTeAP 的原始支架。检查它们在溶液中的光物理性质显示蓝色荧光,λ em = 416-426 nm。通过磁性标准对这些化合物中芳香性的理论研究证明了在外围存在占主导地位的 14 电子电路。
