Azuperylene: The Nonalternant Isomer of Perylene
Abstract
Abstract The isoelectronic isomer of perylene, hereafter called as azuperylene, has been prepared. Electronic structure analysis reveals that the new isomer can be described as a union of two antiparallel azulenes in which the azulene‐type aromatic character of the starting azulene is partially retained. Four 2,8‐dialkoxy (i.e., ethoxy, n ‐butoxy, n ‐hexyloxy, and n ‐octyloxy) functionalized derivatives of the new isomer core have been prepared. The solid‐state structures of the new compounds have been resolved showing exceptional herringbone π–π stacking ideal for charge transport. Organic field‐effect transistors on sublimated substrates display an excellent hole transport mobility up to 1.03 cm 2 V −1 s −1 that largely surpasses that of perylene and reveals the great potential for charge transport of this new class of nonbenzenoid compounds.
