A phenomenon in which a huge potential difference is generated in the film thickness direction due to spontaneous orientation polarization (SOP) simply by vapor deposition of molecules with permanent dipole moments is known as Giant Surface Potential (GSP). The intermolecular force that induces the orientational order and the dipole-dipole interaction that suppresses the orientational polarization are considered to be factors for the formation of SOP. In this study, we take up organic molecular thin films with intermolecular hydrogen bonds stronger than the van der Waals force, investigate whether an effective GSP can be obtained from hydrogen-bonded molecular groups, and examine their potential as SOP materials.
