Front Cover: Thiophene‐Fused 1,4‐Diazapentalene: A Stable C=N‐Containing π‐Conjugated System with Restored Antiaromaticity (Chem. Eur. J. 65/2021).

Keywords: antiaromaticity; diazapentalene; imines; conjugation; thiophenes EN antiaromaticity diazapentalene imines conjugation thiophenes 16057 16057 1 11/24/21 20211122 NES 211122 B The strength of the antiaromaticity of the title compounds b is represented by the power of a phoenix. Antiaromaticity, diazapentalene, imines, conjugation, thiophenes This is a metaphor for the fact that the antiaromaticity of the 8 -electron system pentalene is substantially impaired by nitrogen doping, but is restored by the condensation of thiophene rings.
