A MOLECULE ELECTRONIC DENSITY ON THE DIPOLE MOMENT OF UNIT CELL AND HOLE CONDUCTIVITY OF THIN POLYCRYSTALLINE FILMS OF ANTHRONE AND ANTHRAQUINONE The electronic structure of anthrone and anthraquinone molecules in the gas state and in the simulated crystal unit cell were calculated with time dependent-density functional theory (TD-DFT) method. The values of dipole moment of single molecule and of single crystal unit cell were also determined with TD-DFT method. The results of TD-DFT were compared with known crystal structures of both compounds [1,2]. For both molecules it was observed improvement of matching the length of corresponding bonds when calculated for the unit cell. Unexpectedly high value of dipole moment was calculated for the single unit cell of anthrone. This fact can be responsible for the nano-dimension properties of anthrone as the carriers mobility or high boiling point.
