6-ジブチルアミノ-1,3,5-トリアジン-2,4-ジチオール真空蒸着膜構造に及ぼすCr酸化表面の影響 The Influence of Oxidation of Cr Surface on Formation of the Deposited Films of 6-Dibutylamino-1, 3, 5-Triazine-2, 4-Dithiol
Films of 6-dibutylamino-1, 3, 5-triazine-2, 4-dithiol (DB) were formed on deposited Cr substrates by the conventional vacuum deposition method. The deposited Cr substrates were exposed in air for various times. The adsorption of DB molecules was investigated using XPS to examine the influence on the oxide Cr surfaces. The results showed that C, N and S of DB molecules were bound to the metallic Cr surfaces, and formed disulfide bond. It is assumed that the adsorptions of DB molecules were occurred through the triazine ring to the surface, and formed the polymeric DB on the surfaces. From the XPS spectra, it was shown that DB molecules did not reacted to the Cr oxide surfaces. So it was thought that DB molecules physically react to the oxide surfaces as a structure of monomeric DB. Further, the roughness of DB films was investigated using AFM. It was shown that the DB films were changed into the smooth surfaces with increasing the thickness of the Cr oxide films. It was understood that there were influences in not only the chemical structure of DB molecules, but also the roughness of DB films.
