| Research Abstract |
The purpose of this study is to investigate metal atom behavior on the organic surfaces with a low glass-transition temperature (Tg), especially a photochromic diarylethene (DAE) surface and the polymeric surface. We investigated the metal deposition nature on the polymer surfaces with various Tg and found that a variety of metal vapors including Mg, Mn, Pb, Al, In desorbed from the polydimethylsiroxane surface. The viscous surface showed easier desorption of metal vapor atoms than the elastic surface with the same Tg. On the other hand, noble metals including Au, Ag, and Cu did not desorbed from the low-Tg DAE surface at 50oC but were incorporated to the film and formed nanoparticles. The large difference in the size was generated depending on the isomerization state of DAE.
