Abstract: In situ synchrotron-based near-edge x-ray absorption fine structure measurements and photoemission spectroscopy have been used to investigate the effect of molecular orientation on the interfacial dipole and the energy level alignment at the interfaces of organic heterojunctions comprising copper-hexadecafluoro-phthalocyanine (F16 CuPc) on both standing-up and lying-down copper(II) phthalocyanine (CuPc) thin films. It is found that F16 CuPc thin films adopt the same molecular orientation of the underlying CuPc thin films. An interfacial dipole of 0.45 eV forms at the interface of lying-down F16 CuPcCuPc on highly ordered pyrolytic graphite. In contrast, a much larger interfacial dipole of 1.35 eV appears at the interface of standing-up F16 CuPcCuPc on octane-1-thiol terminated Au(111). © 2008 American Institute of Physics.
