    • Band structure calculations are generally presented in high symmetry directions of the bulk crystal, which are not necessarily the important directions, for example, to charge transport, or the experimentally accessible directions. In this case, the calculations are for the measured directions parallel and perpendicular to the molecular axis

    • Whereas structural studies have concluded that 6P is on average planar in the solid state, our measurements on numerous films on a variety of substrates always yield the ionization potential (IP) of the twisted conformation when the molecules are oriented parallel to the substrate. In contrast, films of upright molecules [6P(001)] yield a higher IP, in keeping with a planar conformation. The observed twist, we believe, is the result of a novel surface reconstruction of these molecular crystals, lowering the total energy.
