トリアジンジチオール蒸着薄膜の配向制御 Orientation Control of Triazine-di-thiol Thin Films by Vapor Deposition
6-dibutylamino-1, 3, 5-triazine-2, 4-dithiol (DB) was vapor-deposited onto Fe substrates. The monomeric DB and polymeric one (PDB) were employed as the deposit source. The molecular orientation, film thickness and bonding state of the formed thin films were characterized using FT-IR, ellipsometry and XPS. Ratio of perpendicular orientation and concentration of dimerized molecules in the films significantly increased at evaporated temperature with changing the source material from DB to PDB. From this fact, it is suggested that the control of molecular orientation in the DB thin films can be achieved by varying the molecular weight of the source materials and substrate temperature.
