K‑Conjugated Dibenzoazahexacenes

The
synthesis and properties
of two highly stable K-conjugated dibenzoaza­hexacenes are reported.
Single-crystal X-ray, optoelectronic, and electrochemical characterization
combined with theoretical studies show a favorable molecular packing
and an optimal energy alignment of their frontier orbitals for charge
transport. Electrical characterization illustrates that the preferential
transport of holes or electrons depends on the number of N atoms in
the aromatic framework.
