Abstract
Long range orientational ordering within C(60) monolayers is observed on p-sexithiophene (6P) monolayer nanostripes on Ag(111) at 77 K. Low-temperature scanning tunneling microscopy studies reveal that the C(60)-6P intermolecular interaction constrains all C(60) molecules to adsorb on their hexagons atop 6P molecules. The orientation-dependent bond-to-bond Coulomb interaction between charge deficient single bonds and double bonds with excess charge in neighboring C(60) molecules results in the in-plane orientational ordering and contributes to the lowering of the total energy of the orientationally ordered C(60) islands.
