Selective metal-vapor deposition on photochromic diarylethenes (DAEs) signifies that metals deposit on the colored surface but not on the colorless surface. The selective metal-vapor deposition phenomenon depends on metal species. Mg and Zn show the selective metal-vapor deposition, but Ag deposit on both surfaces. We found that the metal-species dependence deposition correlated with metal-vapor pressure; metals with high vapor pressure were easy to show selective metal-vapor deposition. In addition, we found that Ca which has high vapor pressure deposited on the both of colored and colorless surface due to the reaction between Ca atoms and surface DAE molecules.
