利用核能级和价带区光电子能谱测定了酞菁锰（MnPc）与强电子受体F6TCNNQ之间界面的电子性质。结果表明，该界面发生电荷转移，导致MnPc （F6TCNNQ）在界面处氧化（还原）。我们的数据显示了一个完整的电子转移，没有杂化态的证据。价带数据表明，尽管存在电荷转移，界面仍保持绝缘/半导体性质，这表明存在局域电荷。
Photoelectron spectroscopy in the core level as well as the valence band region has been used to determine the electronic properties of interfaces between manganese phthalocyanine (MnPc) and the strong electron acceptor F6TCNNQ. It is shown that charge transfer occurs at this interface which results in the oxidation (reduction) of MnPc (F6TCNNQ) at the interface. Our data indicate a full electron transfer with no evidence for hybrid states. The valence band data suggest that the interface remains insulating/semiconducting despite the charge transfer, which indicates localized charges.
