/bjnano.10.118 Abstract We report on mixed ordered monolayers of the electron acceptor-type molecule tetracyano-2,6-naphthoquinodimethane (TNAP) and the electron donor-type molecule hexathiapentacene (HTPEN). This investigation was motivated by the general question which type of mixed stoichiometric
a planar orientation on the surface. We discuss the influence of intermolecular charge transfer on the ordering in the mixed structure.

molecules with electron donor and acceptor properties on the Ag(100) surface. The donor-type molecule was 5,6,7,12,13,14-hexathiapentacene (HTPEN, Figure 1a), which is a planar molecule with D2h symmetry [18]. Its crystal structure and field-effect mobilities were reported by Briseno and co-workers [19
