• 論文の詳細を見る

• Local charge distribution around the titanium atom of amorphous and $\alpha$-crystalline TiOPc films was investigated using Ti $2 p$ X-ray absorption and emission spectroscopy. The X-ray emission spectra show two characteristic features that correspond to charge transfer states that result from in-plane Ti–N and apical Ti–O hybridizations. In the amorphous phase, the Ti–O charge transfer state has both localized and delocalized properties, whereas in the $\alpha$-crystalline phase it has only the delocalized property. These different properties evidence the role of the oxygen atom in forming a network with a neighboring molecule and in balancing the total dipole moment in the $\alpha$-crystalline phase.
