<Abstract:> We demonstrate that accurate prediction of the crystal structures of anthracene and its derivatives is possible with the van der Waals density functional. Based on the calculated crystal structures, we investigate their electronic structures and discuss the correlation between crystal structure/molecular configuration and the electronic structure, in particular, the dispersion of the bands composed of the highest occupied molecular orbitals, which are important to discuss the charge carrier transport property.
