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.
