The synthesis of the hitherto unknown peri-heptacene 7-PA is demonstrated by a rational molecular design strategy in which the reactive zigzag edges are kinetically protected. The formation of 7-PA is validated by high-resolution mass spectrometry and in situ FT-Raman spectroscopy. The open-shell 7-PA displays a narrow optical energy gap of 1.01 eV and exhibits a persistent stability (half-life ≈25 min) under inert conditions.

Abstract
The synthesis of the hitherto unknown peri-heptacene 7-PA is demonstrated by a rational molecular design strategy in which the reactive zigzag edges are kinetically protected. The formation of 7-PA is validated by high-resolution mass spectrometry and in situ FT-Raman spectroscopy. The open-shell 7-PA displays a narrow optical energy gap of 1.01 eV and exhibits a persistent stability (half-life ≈25 min) under inert conditions.File in questo prodotto:
