Electronic structure of polyacenacene. A one-dimensional graphite

The investigation of the electronic structure of polyacenacene (PAA) has been performed on the basis of the tight-binding SCF-MO (self-consistent field-molecular orbital) method. The predicted skeleton for PAA is of an aromatic structure without the band gap. Hence it can be considered that PAA will show the metallic property. In this connection one could regard PAA as a one-dimensional graphite.
